Reinstalling the Port Concentrator

Sometimes the following trick helps to fix errors with USB: Right-click on the “This computer” icon and select “Control”. This will open the Computer Management system snap-in. In it you need to select the “Device Manager” section:

Here we find the section “USB Controllers” and open it. We need the item “Root USB-hub. Click on it with the right mouse button and select the item” Disable “. Close the window and restart the computer. Return to the manager and turn on the hub. all USB ports should work without problems.

Outdated drivers and BIOS

Very often, outdated or incorrect drivers are to blame for a bus failure. This is especially noticeable when updating the system, when everything worked fine on the old OS, and after the update on Windows 10, glitches began with error 43 and the messages “The device is NOT recognizable”.
To fix it, you need to go to the motherboard manufacturer’s website, look for a new software version and install it.
An alternative option is to download the online Drivers Solution Pack client and launch the driver updates using it.

Usually, after this, malfunctions are eliminated finally and irrevocably.

I also want to tell you about a couple of cases when problems with USB ports on Windows 10 appeared due to an outdated BIOS version. And both times it was not in old decrepit pieces of iron, but in new ASUS laptops after updating the pre-installed G8 to Ten. Everything was solved by downloading the latest BIOS version from the official website and flashing the motherboard using a special utility that came with the kit.

Power scheme settings

This case is especially true for owners of notebooks, netbooks and ultrabooks. The fact is that in order to save battery power, the function of selectively turning off devices is activated, and if at a certain point in time a lot of consuming gadgets are connected to the computer (phone charging, card reader, portable speaker, etc.), then Windows 10 can selectively disable one or more devices together.

To disable this option, go to Device Manager again and open the properties of the root USB hub. On the “Power Management” tab, uncheck “Allow this device to be turned off to save energy.” After that, close the manager and reboot.

Solving problems with USB ports in Windows 10

After installing the Windows 10 operating system on your computer or migrating to it from previous versions, it may happen that peripheral devices connected via USB ports often turn off or stop working correctly, while displaying warning icons in the form of a yellow triangle in the device manager, as well as error code 43 in the description.
What to do in this case? First you need to identify the culprit.
Of course, if several devices fall off at once, then it is clear that they are most likely NOT to blame and the reason lies in the computer itself. If only one device is buggy, then the following manipulations need to be performed for diagnosis:

So, we came to the conclusion that the reasons for the problem with USB ports are hidden in the computer. Let’s look for them!

Solving problems with USB ports in Windows 10: 35 comments

Try updating your drivers with Driverspack solution.

Hey. After updating Windows 10, such a glitch appeared, does not see the “headphone amplifier”, (the headphones are connected through the amplifier) ​​Until you pull out and plug in a new USB wire, I tried to stick it into different USBs does not help. And I began to get out here such an error Expertion EControllerError in modules USB_HID.Dll at 0005483E

Try to connect it to the second computer. it is generally working?

kind.
In short, I turned off the usb controller) the mouse and keyboard to usb. I reinstalled Windows from 10 to seven. Now there are no Windows USB drivers and a bunch of other drivers flew) and I also disabled USB. What now?)

Hello. Put the top ten back and DO NOT suffer.

After installing DriverHub and updating the drivers with it, all USBs stopped working, as I understand something happened to the HUB driver. And what to do now if there are no PS / 2 sockets. reinstall the system?

Try the top ten and check with the built-in drivers. If it does NOT work anyway, then most likely the controller is dead.

Hello. Reinstalled Windows 10. In the initial settings (region, language, etc.), neither the keyboard nor the mouse works. And I don’t even know what to do. I tried to switch connectors. The backlight is on but there is no cursor on the screen. There is a response to keystrokes. (In System Restore, everything works, but the cursor also does not appear)

Hello. We tried to connect another mouse?

Twenty PCs: MAG Z390 Tomahawk, i59600K, 1X16 Gb ddr4 2400, GeForce 2080 and one ORICO A3H4 Windows 10 x64

The problem is this: We decided to abandon the use of USB 3.0 ports in ACER monitors due to Incorrect operation of the built-in USB hub (the image disappeared on the monitor for a few seconds and it could be so every ten seconds). And also when connecting Patriot viper 370 headsets and two models 1more: H1007 and H1005 had problems when trying to listen to the microphone in the sound settings of windows 10, the microphone turned off and the OS itself began to freeze. When rebooting, the NK did not reboot, but SIMply worked WITHOUT displaying a picture (I had to reboot the device)

We decided to purchase an ORICO A3H4 with external power supply (sinned about the lack of power for the headsets) and lo and behold! Everything is working! But the euphoria did NOT last for a long time (when the checkbox “Listen from this device” is turned on, the microphone goes out and the sound control panel hangs tightly. Disconnecting the headset from the hub helps. If you DO NOT disconnect the headset from the hub, the PC will come out of overload only by pressing the restart button.

When you connect headphones directly to the board or to the 3.0 connector on the front panel, all problems disappear.

Help me figure out the reason! I’ve already broken my whole head!

Hello. Where would I start:
1. I checked if there are BIOS updates for the motherboards and, if any, updated on one PC and looked at the result.
2. if the BIOS of this board has the ability, then they would completely disconnect USB 3.0 and see how it works on USB 2.0
3. I tried to use a separate board with a USB controller and would connect a hub from it. will it make a difference.
Something like that.

Thanks for the advice. Shut down on a dell win 10 USB 3.0 laptop shutdown host controller with reboot fixed the problem, turned on.

On a computer Win 10 and all usb 3.0. I had to pick up a Xerox WC 3025 printer that supports 2.0. All the things with a daw in the BIOS, the wires have been checked, it remains to ask the society what can be done. For example, maybe a psi board with 2.0 ports?

Yes, I would put the board with a separate controller.

USB port does not work after reinstalling Windows

And if it’s USB drivers?

It happens that a problem with USB ports is a symptom of a more complex and unpleasant breakdown. For example, this can signal the failure of the laptop motherboard chipset. specifically, the breakdown of the south bridge. After all, it is the south bridge (I / O Controller Hub) of the laptop motherboard that is responsible for the peripherals. USB, SATA (IDE), Audio, PCI, Ithernet. Occurs due to: overheating, short circuit on the board, problems with the power supply, mechanical stress.

A SIMple test will help to test the hypothesis about the failure of the chipset: you need to select the USB ports on the laptop, painted in black, i.e. USB 2.0, and check their functionality. If USB 2.0 works, but USB 3.0 is available, the problem is only with the drivers.

Why do USB ports stop working after reinstalling Windows on new laptops. How to fix this problem yourself? What else you need to know about USB related crashes?

In order for the user to be able to quickly navigate the malfunctions of the USB controller, I will conduct a small excursion into the terminology of this issue.

USB (u-es-bi, English Universal Serial Bus) is a universal serial bus for connecting peripheral devices to a computer via a four-core cable. With this technology, it is possible to connect devices without their own (autonomous) power supply only due to the power supplied through this bus. All of these devices are familiar. external hard drives, USB flash drives, adapters, etc.

Until recently, USB 2.0 was predominantly installed on devices. The slower and more powerful USB 2.0 is gradually being replaced by USB 3.0 with a data transfer rate of up to 5 Gb / s (up to 5 Gb / s) and a power supply through the bus up to 1 A (1 Ampere). Recently, the USB 3.1 standard began to be implemented. progress DO NOT stop.

How to fix a problem with USB 3.0 drivers?

For example, you installed Windows 7, and USB 3.0 did NOT work even when installing all updates (drivers) from the MicroSoft website. Further, there are two outputs: either by installing Windows 8/10 and at least USB 3.0 will most likely work immediately, or you will have to look for drivers for the USB controller installed in your laptop. You will have to do this on the Internet, so you will need high-speed Internet access.

What Windows OS will USB 3.0 NOT work on?

This problem is typical for the operating systems Windows XP and Windows 7. But in Windows 8 and Windows 10 this problem is practically NOT encountered. The reason is SIMple: USB 3.0 began to be implemented en masse after the release of Windows XP and Windows 7. But if in Windows XP the problem of non-working USB ports does not resolve on its own, then in Windows 7 you can try to solve the problem by SIMply turning on automatic updates for Windows. The system itself, by the device ID (USB 3.0 controller ID), will recognize and install the driver, provided that the brand of the controller and the manufacturer is “known” to Windows 7.

USB 3.0 support by default Not available on all operating systems

On newer laptops, USB 3.0 ports are blue, while USB 2.0 remains black. An astute and quick-witted user could almost immediately assume that the problem lies precisely in the new USB 3.0 standard, which has not yet been fully implemented at the software level. THOSE. The hardware part of USB 3.0 is already implemented in the laptop, but the software (driver) is not yet.

Therefore, already now it is possible to give an answer to the main question of this article: “Why USB does not work in the laptop after reinstalling Windows?” “Because there are drivers for USB 3.0 ports in the Windows operating system”.

Where to find drivers for USB 3.0 (3 sources for)

  • Log in to the manufacturer and find the driver you want by searching the website. Here you need a little experience: first of all, you need to know what to download (it makes no sense to install all the drivers in a row) you need to know the exact brand of the laptop (name and alphanumeric index) the bitness of the Windows 32 or 64 bit operating system;
  • Download any driver-pack and install all drivers using it. For example from here. https://drp.Su/ru/download.Htm;
  • Go to this site https://devid.Drp.Su/?L=ru (click the link at the bottom. I am looking for a driver by hand) or to this https://devid.info/ru and find, download and independently install the necessary driver

The first method from the entire list is the most preferable and, possibly, easy, if everything is unambiguous on the laptop manufacturer’s website and you have fast Internet. But sometimes you can find a whole list of USB drivers for one device and no hint as to which of THESE files should be downloaded and installed. Therefore, the second point with the driver pack can help sometimes much faster. if the Internet is fast (you have to download several gigabytes of software). In this case, you will have drivers for all occasions for a computer, laptop, netbook.

If there is a fast Internet connection, then it is best to clean (with the formatting of the C 🙂 drive the Windows installation is carried out after some preparation, i.e. Creating a backup (backup) of files and drivers. Otherwise, you may find yourself in a situation where there is no way to download drivers, since the network interfaces in the laptop do not work, and you cannot copy the driver pack from a flash drive (external drive), since everything is USB 3.0 on the device. and they do not work.

If USB ports don’t work after installing Windows

Most often, the problem with not working USB connectors after installing the OS occurs in those users who are installing a clean Windows 7 computer or laptop, which has only USB 3.0 connectors. The reason is the absence of appropriate drivers by default in 7. However, SIMilar problems can arise in Windows 10, especially when it comes to some unique hardware.

The general solution is to check if there are separate chipset and USB drivers on the official website of the laptop or PC motherboard manufacturer. If so, install them. For Windows 7, if no official driver is available, you can find generic USB 3.0 drivers on the Internet.

USB ports not working on a Windows 10 computer or laptop. what to do?

One of the common problems on a PC or laptop with Windows 10 and previous versions of the system is the USB port does not work or all USB connectors at once. The reasons can be very different, but it can arise after installing Windows, changing PC components, or without any specific preceding actions.

This manual describes in detail what you can do to fix the situation when USB ports do not work, as well as what may be causing it.

  • Does NOT connect to a specific USB device, or the connection via a cable, extension cable or USB hub does not work
  • USB on the front of the computer does not work
  • Only one or several USB ports do not work (for example, only USB 3.0)
  • If USB ports don’t work after installing Windows 10
  • Other Possible Problems and Solutions

One or more USB connectors are not working

In the event that only one USB connector does not work on your computer or laptop, the first assumption is a malfunction (and it may be “inside” and a superficial examination will NOT reveal it), damaged, oxidized or dirty contacts of this connector.

It can also be a “burnt” port, which can sometimes be noticed by visual inspection of places inside a PC or laptop in the area where this connector is connected to the motherboard. Sometimes the USB controller chip can be damaged, and not located in the immediate vicinity of the connector itself. However, visual inspection can not always give a result and here it is worth contacting the workshop.

If a group of connectors does not work in your case, this may be either hardware damage to the USB controller chip, or SIMply the absence of original drivers for the USB controller from the manufacturer of the laptop or PC motherboard. In this case, I recommend downloading them from the manufacturer’s official website and installing them manually, and even if the website has drivers for Windows 10, we can safely install them for 7, 8 or 8.1.

Note: if you are in doubt as to whether the USB connector is a hardware problem or the system is installed, an easy way to check it is to make any bootable USB flash drive, plug it into this connector and check if it is visible in the BIOS. If so, is it booting from it? If the drive is visible, loading is in progress, then the hardware is in order, we are looking for a problem in the system, Install the original drivers on the chipset and, if available on the official website, on the USB controllers.

If specific devices are NOT connected via USB, as well as in problems with cables, hubs and USB extenders

Often, the user plugs in a particular USB device and, when it is NOT functioning normally, concludes that the USB port is not working. This is often not the case, and here I recommend trying:

  • Check if other flash drives, mouse, keyboard work with this USB port?
  • If you use a hub (splitter) for the connection, try connecting the device directly to the USB connector.
  • If you use a cable to connect (for example, connect a phone), try with a different cable. The bottom line: some USB cables do not serve for data transmission, but only for charging: for example, you can find these in a set with wireless headphones or some toys.
  • When connecting a device, check if a new device appears in the device manager with an error (exclamation mark)? If it appears, open its properties, look at the error code and search for it to solve the problem (including on this site), for example, common: Device descriptor request failed (Code 43), Windows has stopped this device (Code 43), the driver is damaged or missing (Code 39), The device does not work correctly (Code 31).
  • The problem may also be in the USB connector on the device itself: a malfunction, dirt or oxidation of the contacts can lead to the fact that it will NOT be visible in Windows (sometimes while it continues to charge or glow).

As a result, if we are talking about a specific device, I recommend looking for solutions specifically for this device: this will allow you to narrow the available set of options for the problem and the corresponding actions to fix it.

What to do if USB on the front of the PC does not work

Another common situation is that all connectors are functioning properly, but the connection to USB on the front panel of the computer will lead to nothing. Almost always the reason for this is that these connectors are NOT cabled to the “internal” USB connector (pictured below) on the motherboard.

About this in detail and with photos in the second part of the instruction How to connect the connectors on the front of the computer to the motherboard.

Additional manifestations of the problem and methods of correction

Finally, some additional Possible ways to fix the problem:

  • If the problem appears after shutting down Windows 10, and if you run “Start”. “Restart”, USB works again, try disabling Fast Startup.
  • Check if the BIOS / UEFI of your computer or laptop has USB fast initialization, fast boot options. If so, try disabling them.
  • In Device Manager, under USB Controllers, check the properties of all USB hub devices and on the Power Management tab, uncheck “Allow this device to be turned off to save power”.
  • If the problem appeared recently for no apparent reason, check if there are system restore points as of the date when everything worked, if any. Use them.

In a situation where none of the proposed options turned out to be useful in your case, describe the details in the comments: maybe I can give a hint.

Causes of the problem when USB ports on a laptop do not work

If you do not know what exactly caused the indicated problems with USB ports, then consistently follow the whole complex of the tips listed by me, this will help to effectively solve the problem with the malfunction of the USB ports on your PC.

    USB may be disconnected due to system settings

    The power management of the laptop can be configured in such a way that the system itself disconnects the USB connector after a certain period of inactivity to save battery power. No repairs are required here. In order for the laptop to stop disconnecting the USB input, it is enough NOT to allow Windows to change the controller’s power settings, for which:

    • In the manager, open the branch of serial bus controllers, select the line of the root USB hub.
    • Double click open the device, select power management.
    • Uncheck the box next to the line allowing the system to disable the connector to save power.

    Repeat the described steps for each of the USB hubs registered in the device manager.

    We work with the device manager

    Through the “Start” or otherwise, go to the device manager. Perhaps one of the group of USB controllers here is marked with a yellow exclamation mark icon, why the device is NOT functioning.

    You can try to fix the situation in the following way:

    • Remove the controller marked in yellow from the dispatcher;
    • Reboot your laptop.

    At the next start, the system will reinstall all the necessary software, after which the controllers that have failed can work again. Sometimes it helps to rollback the OS to a previous state when all the equipment was functioning normally.

    Problems with the driver on the motherboard

    Sometimes USB not working problems can be caused by an outdated motherboard chipset driver. The problem is solved by downloading it from a reliable source and then installing it. For this:

    • Find out your board and chipset model. If the documentation for the laptop is NOT saved, install a diagnostic utility such as AIDA64. When you have a chipset from Intel (in most cases this is the case), then all the necessary information can be obtained at http://www.Intel.com/support/ru/siu.Htm, downloaded there a proprietary utility from Intel to identify equipment.
    • The required driver can also be found on the motherboard manufacturer’s website. However, even here it may NOT be the freshest. Guaranteed its latest version can only be found on the website of the chipset manufacturer.
    • Then it remains to unzip the driver, for example, using the 7-Zip utility and install it as a normal application.

    If you don’t want to bother finding the latest version of the driver you need, you can SIMply use the DriverPack Solution application, which automatically detects devices with outdated drivers and updates them.

    Fixing usb ports on a laptop

    The reasons why USB ports on a laptop do not work can be both software and hardware. Sometimes all ports are NOT functional at once, and sometimes only one or two. Below we will consider why such malfunctions appear, and also tell you what to do to fix them on your own, if you do not need to repair the connector itself.

    Checking BIOS configuration

    When this problem occurs, the first thing to check is whether the USB controllers on the motherboard have turned off. They may well turn off on their own, and repair of the connector is NOT required. When the controller suddenly stopped working, you can activate it in the BIOS:

    • Immediately after starting the boot, frequently press Del, F2 or another function key provided for entering the BIOS on your device.
    • Find Integrated Peripherals or Advanced (depending on BIOS version).
    • Select USB Configuration. Here, opposite the USB Controller lines, the Enabled parameter should be set. If not, set the desired value yourself and save the current configuration.

    The problem can also sometimes occur due to some USB device that needs repair. To determine it, Disconnect all devices using this port. mouse, USB keyboard, etc. Try plugging in a working flash drive. If problems stop appearing, look for a non-working peripheral device.

    When Windows is to blame

    Sometimes OS crashes are a prerequisite for non-functioning controllers, so repair is required by Windows itself. In this case, you need to reinstall. But to be sure of the cause of the malfunction and NOT do unnecessary work, check the functionality of the USB ports, and do not load Windows.

    To do this, you can, for example, boot the system from any Live CD. If in this disk OS the ports work as expected, then the problem is definitely in Windows. you can safely reinstall it. If the devices did NOT work when booting from the Live CD, then the problem should be looked for in the hardware, it may need to be repaired.

    So, most often, software malfunctions with non-working USB controllers are solved by updating the driver for the chipset or the motherboard (which is essentially the same thing after the north and south bridges on the motherboard have been replaced with one chip). Also, the problem often goes away after reinstalling the OS. Otherwise, the faulty controllers may be directly connected to USB-devices, or repairs must be done on the motherboard itself.

    Incorrect BIOS settings

    To reinstall, you need to change the parameters of the low-level operating system. In the process, you can accidentally turn off the USB controller. This can happen arbitrarily. To return the settings to the required state, you should:

    • Restart the computer and, at the start of the boot, press Esc, and then F
    • Find tab
    • In the USB Configuration section, set the Enabled parameter to all USB Functions and Cotroller items.
    • Sometimes the inclusion is hidden in the Port Options item, in which you need to check the USB Port option.

    After completing the manipulations, it remains only to press F10 and leave the BIOS with saving the settings.

    What to do if USB ports on an HP laptop do not work after installing Windows 7

    Problems in the operation of USB connectors after installing Windows 7 are most likely related to the lack of necessary drivers. Modern laptops work with USB 3.0, and the G7 does not support this standard.

    The most obvious way out is to install chipset drivers compatible with the installed OS version and supporting USB 3.0. You can find these on the HP support site, indicated the model number of your laptop. Then download the chipset drivers and install them. After rebooting, the connectors should work. An alternative option is a special utility HP Support Assistant or the official website of the chipset manufacturer.

    Installing drivers without previous ones

    If just installing new drivers did not help, then it makes sense to try the “clean version” of the procedure. To do this, press WinR and enter the devmgmt.Msc command in the Run window, which will open the device manager.

    In the list of available devices, find the item “USB Controllers” and delete all items in the name of which there is a Host Controller, and then install the drivers. Then restart the computer and check the result.

    Disable selectively suspending power to ports in the system registry

    There may be an entry in the system registry that instructs to stop powering the USB ports to save power. Its value needs to be changed. To do this, click WinR and use the regedit command.

    In the registry editor window, press CtrlF and in the search bar enter DisableSelectiveSuspend.

    After a few minutes of searching, the editor will show the found entry (or will not show it if it is not there). It should be located at HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services USB. According to the found entry, you need to name it with the right button and select the “Change” item, then set the value to 1 and save the change. Then close the editor and restart the computer.

    Least favorable option

    There is a small chance that the south bridge, one of the chipset components, has failed during the installation process. As a rule, the same USB controller is built into it, which is responsible for the operation of the corresponding ports.

    It will NOT work to replace the chip at home. this requires a special infrared soldering table and skills in working with it. That is, you have to contact the service center.

    USB Ports On Laptop Not Working

    Check Warranty

  • Urgent device repair
    from 30 minutes
  • Physical damage

    In most cases, this type of malfunction requires specialist intervention. This category includes:

    • Physical damage to the USB port;
    • Open or short circuit of the supply wiring inside the system unit.

    The worst thing that can happen is a malfunctioning “south bridge” on the motherboard. This hub is responsible for connecting all computer peripherals and at home without Special skills and tools it is impossible to repair it.

    External hubs

    Many users use external USB hubs. Someone, so as not to climb under the table every time to connect a new device, and someone. due to the lack of ports on the laptop.

    If at the same time you are faced with periodic failures of external equipment, pay attention to the screenshot. Several devices connected to the hub at the same time may exceed the allowed power. The system, being unable to supply more than 500mA to the power port, will shut it down to avoid overloading or burning out. The way out of the situation is SIMple. Disable unnecessary or use external self-powered storage devices.

    Programming methods

    First of all, don’t forget that you are using Windows. Suddenly, for no external reason If a problem occurs, you can fix it with a SIMple reboot. By the way, this is an official Microsoft recommendation posted on the technical support page. On a laptop, this operation can be performed using the keyboard shortcut “Alt” “Ctrl” “Del”. On the desktop, when the keyboard and mouse do not work, press the “Reset” button located on the case.

    BIOS (or its modern version of UEFI) provides an entry-level interaction between computer components, even before the OS boots. Therefore, if a good controller is disabled in it, the system considers that it does not exist. You can check the status of the ports by entering the BIOS at the time of reboot.

    Further user actions are focused on finding the section responsible for USB support. It contains the parameters that regulate the operation of the controllers. It is up to the user to make sure they are all enabled.

    As you can see in the screenshot, the switch of one of the items is in the off position. In our case, it is responsible for supporting USB keyboards on older OS. As a reminder, the BIOS does not support mouse operation. You have to navigate the menu using the arrows on the keyboard and function keys.

    Turn on the controller and do not forget to write down the changes made. The function key responsible for this action is underlined in the right part of the window.

    UEFI, as the modern BIOS version, supports the use of a mouse in the graphical interface. It is easier for users to work with, and the actions performed are SIMilar to those already described. Please note that the required item responsible for the operation of the serial bus is located in the same section Advanced.

    We check the status, record the actions and exit. After reboot, previously disabled USB ports will start working.

    It is unlikely that a well-functioning port would change its hardware configuration overnight. For this reason, the method should be used on a computer like you are seeing for the first time or in “public” use. Who and what “regulated” there to you is unknown. Therefore, if the USB ports do not work on it, it is worth looking at the hardware configuration.

    Enabling Extended USB Support in the BIOS may come in handy when you decide to Reboot into Safe Mode. Otherwise, you risk being left without input. The computer will start, and the keyboard and mouse will refuse to work.

    What to do if USB ports don’t work?

    Developed at the end of the last century, the USB universal serial bus standard gained popularity quickly enough. The main task set by its developers was to unify the connection of peripheral devices. After 20 years, users no longer remember, and many do not even know about such interfaces as PS / 2, COM and LTP. All peripherals, except perhaps monitors, are connected to the PC through this connector. Therefore, when it turns out that the USB ports do not work in the computer, a quiet panic begins in users.

    Power supply

    In some cases, the problem may appear after upgrading the hardware configuration. By replacing the card and installing an additional powerful cooler, some users forget about the power supply. As a result, it ceases to cope with the load at peak times. In other words, as soon as the coolers reach their maximum speed, you will lose power to the keyboard and mouse. The system will determine them as lower priority if the processor is overheated. The way out is SIMple. change the power supply to another with a power reserve of approximately 20-25%.

    Windows 10

    Windows 10 USB port issues are largely an artificially bloated issue. At the time of its release, Microsoft was actively promoting it as a system that works on almost any hardware. Indeed, her system requirements are quite democratic. As a result, users who missed Windows 8 for aesthetic reasons began to install it on devices that had not been updated for a long time and problems began to fall.

    In fact, Windows 10 is based on the same NT kernel as its predecessor. Consequently, her “diseases” are only hereditary. All methods described for Windows 7 are guaranteed to work in it. Finding the Device Manager in the wilds of the new menu can be a problem.

    The screenshot shows the sequence of such a transition. First, in the left corner, select “About the system”. Then in the right. “System Information”. You get an old-style window with a link leading to the device manager.

    Check yourself

    In large corporations, in which hundreds of people work with complex equipment, there is a tradition of writing instructions for all occasions. This does not always help, but they have a wonderful wording: “. When a malfunction occurs, you must make sure that it is NOT the result of wrong actions.” This should be understood literally. If you plug your printer into a USB port and it doesn’t work, don’t rush to panic. See where the other end of the cord is. He can lie behind the printer, jumping out of the port. A flash drive that does not open may be faulty. If everything is done correctly and the USB still does not work, proceed to the next step.

    Windows 7

    You can enable USB ports on Windows or check the operation of controllers in the operating system itself. This will require opening the Device Manager. You can get to it in several ways. For example, open the control panel.

    Use the context menu for the My Computer icon. Select the Checked item and go to the description of the properties of your computer.

    In the window that opens, select the Checked item.

    Finally, you can use the “Run” menu.

    Typed the command given in the screenshot, you open the device manager directly.

    At the top of the window there is a button that is responsible for a quick update of the entire hardware configuration of the PC. As a result, the computer will again poll the equipment and will be able to detect the device that has stopped working. For example, in this way you can force the computer to look for a driver for a flash drive, which was NOT determined on its own.

    The second use of the Device Manager assumes that polling the equipment did not produce any results. This technique is more stringent and requires software removal of controllers.

    Sequentially selecting each, calling the context menu and removing the driver. At the same time, one must be prepared for the fact that the keyboard and mouse are also USB devices and may stop working. When faced with this situation, reboot. Remove Controllers That Did Not Have Time And Restart Your PC Again. The Windows USB port driver will recover automatically when the computer starts up. If the reason was precisely in it, after reinstallation everything will work.

    Microsoft regularly releases updates, but many users disable this feature for various reasons. Basically, the effect of “memory of generations” is triggered. In the era of widespread use of pirated copies, this was the way to achieve system stability. As a result, without receiving an update, the USB driver for Windows may SIMply become outdated.

    The screenshot shows the control menu that is available for each controller if you select the “Properties” item. Using the highlighted buttons, you can view information, update USB drivers, downgrade or uninstall them.

    A malfunctioning or unrecognized Windows device in the manager will be indicated by a yellow triangle with an exclamation mark. Having found such an icon on the USB controller, you should use the above driver management menu.

    Another problem is faced mainly by laptop owners. It consists in the fact that when the computer is working properly, when it comes out of sleep or hibernation mode, the USB ports “fall off”. In other words, you work quietly, then, after closing the laptop lid, waste on other matters. When we return, we find that the connected peripherals refuse to work. This behavior is not due to malfunctions, but to the peculiarities of power management.

    The screenshot shows the reason why USB ports are disabled in Windows. When the laptop is running on battery power, the system may turn off the hub to conserve power. The reverse operation should be done automatically after connecting the power adapter. In practice, such a scheme does not always work. Therefore, if the specified item is ticked at you. Uncheck it, disabling the port shutdown in saving mode.

    Hardware faults

    If the software methods did not help, then the malfunction lies in the hardware. Let’s consider the most likely problems that you can face and ways to solve them.
