Lack of driver
It happens that the computer does not see the printer via USB due to the lack of a driver or due to improperly installed or outdated software.
Go to the manufacturer’s official website, download the driver for your device from there and install it. Then restart your computer and try to print a test page.
If you accidentally installed an unsuitable driver, go to the “Device Manager” through the control panel, find the necessary hardware there, go to its properties, then to the “Driver” tab and click on the “Uninstall” button. After that, install the new software downloaded from the manufacturer’s official website.
The computer does not see the printer via USB: how to fix it?
The reasons can be many, from an unconnected cable to a failure in the operating system. Let’s consider common problems and their solutions. from simple to complex.
Sometimes a computer or laptop cannot see the printer via USB due to a faulty cable or port, or a bad connection.
- Disconnect the device cable at both ends and then reconnect.
- Check if the USB connector is working properly. Try to connect another device through it: for example, a keyboard or mouse.
- Try connecting the printer to a different USB port.
- If possible, replace the cable.
Also make sure the printer is turned on. Some devices have the power button on the back or side, and users simply forget to press it. Sometimes the computer does not see the printer via USB due to such a trifle, and the solution of the issue takes literally one minute.
Check which hardware is the default for printing. To do this, go to the control panel, then to “Hardware and Sound”. “View devices and printers”. Right click on the printer icon and select the “Set as default” option. In some cases, this is enough for the device to work correctly.
If the problem persists, double-click the equipment icon, in the window that opens, select the “Printer” tab and uncheck the “Pause printing” and “Work offline” items. Also click on “Clear Print Queue”.
If this does not help, go to the control panel, select the “View” menu item “Small icons”, go to the “Administration” tab and open “Services”. In the window that appears, you need to find the “Print Manager” service and set the automatic startup type.
If the service is stopped, click also on the Start button, and then print a test page.
If the printer does not connect to your computer via USB and all of the above methods did not resolve the issue, the problem may be in the hardware itself. Try connecting your device to another computer or laptop. If the problem persists, the best option is to take the printer to a service center for a technician to test and repair it.
Connection problem in Windows XP
Lovers of rare operating systems often encounter problems with USB connection of mobile devices. For example, in Windows XP, the computer does not see the gadget for a very simple reason. this system lacks the necessary components. If you have XP, download the Media Transfer Protocol Porting Kit from www.microsoft.com/en-US/download/details.aspx?ID=19153 and install it. Without this protocol, the phone will not connect to a PC running Windows XP.
Error code 19
After system failures, virus attacks, etc. when connecting a mobile gadget to a computer, the system may display the error “Windows cannot start this device because the information about its settings is incomplete or damaged.” Most often this happens due to changes in the parameters in the registry. Start the registry editor with the regedit command and expand this branch:
In the right column of the editor window, find the UpperFilters parameter and remove it.
After that, restart your computer and try connecting your phone again. If the problem was related to changing its value, the device will connect without problems.
Temporary crashes on Windows or Android
No matter how trite it may sound, but sometimes you can fix connection problems by rebooting the devices. Turn off the computer completely (remove the battery if it is a laptop), do the same with the mobile device. After waiting five minutes, reconnect them to power, boot and try to connect with a cable.
Device driver failure
Eliminate driver problems. When you connect a new device to your computer, the corresponding driver is installed on the system. If there was some kind of failure on the PC or the software was installed to work with peripherals, go to the Device Manager, find your phone in the USB Controllers list and see if it is marked with a yellow or red icon. If so, it will indicate a problem with the device drivers.
Try to remove the marked device and then update the hardware configuration. Also note the device state in the properties. If the status indicates an error, try reinstalling or updating the driver on the appropriate tab in the properties window.
If the phone was connected before, the driver is still in the system and you need to search for it on this computer.
Incorrect connection settings on the mobile device
Everything that was said above was mainly related to the cable, the computer as a base station and the Windows operating system. But the mobile device itself, or rather its incorrect settings or existing problems on it, can cause connection problems. The case when the computer does not see the phone via USB, but only charges it, is a fairly common example of incorrect connection settings.
The fact is that most smartphones and tablets have several connection modes. These are MTP (transfer of any files), PTP (transfer of multimedia files), built-in CD-ROM (connection as a virtual drive with useful software) and charging only (fast battery charging). So, if you have charging mode turned on, the contents of the smartphone in Windows Explorer will not be displayed!
As for the fifth version of Android, in earlier versions there may be other modes, their names may differ, but this does not change the essence. To be able to view the entire file system of a mobile device, including a removable memory card, you must enable MTP mode.
If your computer does not see your phone’s memory stick via USB, try switching from one mode to another. The same applies to the modem mode, in this mode the file system of the PC phone will not be seen.
Note: it is advisable to check the memory card separately. It must have an NTFS or FAT32 file system and not contain logical errors that prevent Windows from recognizing it.
To avoid problems with connecting smartphones and tablets via USB, it is recommended to use special programs. They contain the components necessary to ensure correct feedback and can be used not only for direct USB connection, but also for making various settings. Examples of such programs are Samsung Kies and Nokia Suite.
Universal adb driver
If the computer does not see the Android phone, as an option, you can try to install the Universal Adb Driver into the system by downloading it from the official website adb.clockworkmod.com. It is intended mainly to ensure the correct operation of the Android Debug Bridge and programs for synchronizing a PC with a tablet or smartphone running Android, but, perhaps, it is he who will help solve all your problems with connecting via USB.
Universal Adb Driver will also provide invaluable service if you do not have a tablet or smartphone driver at hand.
- Check your computer for viruses. they can cause inappropriate behavior of USB devices
- Check the Windows registry, namely the key If you see a parameter named NoDrives in this section, remove it and restart your computer.
- Go to the Windows registry key If the StorageDevicePolicies parameter is present, delete it.
- In some cases, a complete blackout of the computer helps. You can do it like this: unplug the flash drives, turn off your computer or laptop, unplug it (or remove the battery if it’s a laptop), and then, while the computer is off, press and hold the power button for a few seconds. Then release it, reconnect the power supply and turn it on. Oddly enough, it can sometimes help.
If everything previously described did not work, and the flash drive does not work on other computers, you may find another article useful: Programs for repairing flash drives (Kingston, Transcend, Sandisk, Silicon Power and others).
Checking the Startup Parameters for the USBSTOR Service
If you disable the USBSTOR system service, the computer will stop responding to the connection of removable USB drives, that is, it will not see any flash drives. You can check the startup parameters of the service as follows:
- Go to the registry editor by pressing the WinR keys and entering regedit
- Go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ USBSTOR
- On the right side of the Registry Editor window, check the value of the Start parameter If it is 4, then the service is disabled. Double click on the parameter and set the value to 3.
- Reboot your computer.
If the cause of the problems with connecting the flash drive was in a disabled service, these actions will correct the situation.
The computer does not see the connected USB flash drive, but there is a connection sound. simple ways to fix the problem
Before starting, I will separately note that further we will talk about cases when you connect a USB flash drive to a computer or laptop running Windows 10, 8.1, 7 or another operating system. If the USB flash drive is not visible in the BIOS or Boot Menu, use a separate instruction: What to do if the computer or laptop does not see the bootable USB flash drive in the BIOS or Boot Menu.
Also, before proceeding, and if your USB drive is connected to the front panel of the PC, via some USB hub or USB extension cable, I strongly recommend trying to connect it directly to the USB connector, in the case of a desktop computer. to the rear panel. In this case, it may make sense to check the operation of the drive both on the USB 3.0 and USB 2.0 connectors, regardless of which version of USB the drive supports. If the flash drive does not work when connected to the front USB connector on the PC, check that the front panel is properly connected to the motherboard.
Also, if you have a lot of connected USB devices (printers, cameras, microphones, etc.), try disconnecting optional devices, restarting your computer and reconnecting the USB flash drive. Just in case, visually inspect the connector on the flash drive: clogged dirt can also be the cause of the problem in question.
Another common simple option in Windows 10 is that a USB flash drive is visible and works properly after rebooting the computer (via Start. Restart), but it ceases to be displayed after using the “Shutdown” item and turning it back on (or putting the computer into sleep / hibernation mode). In this case, try disabling Windows 10 Fast Startup, restarting the system and check if that solved the problem.
Solving problems when opening a flash drive
A common case is that the flash drive is still visible in the system, but it is not possible to access it for one reason or another with the corresponding error messages. Below is a list of instructions for the most common errors of this kind:
The computer does not see the USB flash drive. what to do?
This manual provides details on what to do if the computer or laptop does not see the connected USB flash drive: it does not display it at all (although there may be a connection sound), or it connects, but with errors. First, there are simple ways to fix the problem that may work, then. more complex methods for fixing problems with the connected flash drive. If the methods described at the beginning of the article do not help “cure” the problem, move on to the next. until the problem with the flash drive is solved (unless it has serious physical damage. then there is a possibility that nothing will help).
There are many reasons why you may encounter the fact that the computer does not see the USB flash drive. The problem may appear on Windows 10, 8.1, Windows 7, or XP. If the computer does not recognize the connected USB flash drive, this can manifest itself in different ways: sometimes there is no reaction to connections, sometimes there is a connection sound, but the USB flash drive does not appear in the explorer, sometimes the drive is visible, but it cannot be opened with various errors.
If the USB flash drive does not see Windows XP
The most common situation I encountered when calling for setting up and repairing computers, when a computer with the Windows XP operating system installed on it did not see a USB flash drive (even if it sees other flash drives), was caused by the fact that the necessary updates were not installed to work with USB drives The fact is that many organizations use Windows XP, often in the SP2 version. Updates, due to restrictions on access to the Internet or poor work of the system administrator, were not installed.
So, if you have Windows XP and the computer does not see the USB flash drive:
- If SP2 is installed, update to SP3 (when updating, if you have Internet Explorer 8 installed, uninstall it).
- Install all Windows XP updates, regardless of which Service Pack is used.
Here are some of the fixes for working with USB flash drives that were released in updates to Windows XP:
- KB925196. fixed errors when the computer does not detect the connected USB flash drive or iPod.
- KB968132. fixed errors when, when connecting multiple USB devices in Windows XP, they ceased to function normally
- KB817900. USB port stopped working after removing and re-inserting the USB flash drive
- KB895962. USB flash drive stops working when the printer is turned off
- KB314634. the computer sees only old flash drives that were connected before and does not see new ones
- KB88740. Rundll32.exe error when inserting or removing a USB flash drive
- KB871233. the computer does not see the USB flash drive if it has just been in sleep or hibernation mode
- KB312370 (2007). Windows XP USB 2.0 Support
By the way, despite the fact that Windows Vista is almost never used anywhere, it should be noted that installing all updates should also be the first step when a similar problem occurs.
Windows 10 does not see a USB flash drive after updating or installing
Many users are faced with the problem of not displaying USB drives after upgrading to Windows 10 from previous OS, or after simply installing updates on an already installed Windows 10. It often happens that only USB 2.0 or USB 3.0 flash drives are not visible. that is, one can assume that USB drivers are required. However, in fact, this behavior is often caused not by drivers, but by incorrect entries in the registry about previously connected USB drives.
In this case, the free USBOblivion utility can help, which removes from the Windows registry all information about previously connected flash drives and external hard drives (mount points for USB drives). Before using the program, I highly recommend creating a Windows 10 restore point.
Disconnect all flash drives and other USB storage devices from the computer, run the program, check the “Perform a real cleanup” and “Save the undo reg file”, then click the “Cleanup” button.
After cleaning is complete, restart your computer and connect the USB flash drive. with a high probability, it will be detected and become available. If not, then also try to go to the device manager (through the right click on the Start button) and follow the steps to remove the USB drive from the Other devices section and then update the hardware configuration (described above). You can download the USBOblivion program from the official developer page: https://www.cherubicsoft.com/projects/usboblivion
But, in relation to Windows 10, another option is also possible. a real incompatibility of USB 2.0 or 3.0 drivers (as a rule, then they are displayed with an exclamation mark in the device manager). In this case, the recommendation is to check the availability of the required USB drivers and chipset on the official website of the laptop or PC motherboard manufacturer. At the same time, I recommend using the official websites of the manufacturers of the devices themselves, and not the sites of Intel or AMD to search for such drivers, especially when it comes to laptops. Also, sometimes updating the BIOS of the motherboard helps to solve the problem.
Check if the computer sees the connected USB flash drive in “Disk Management” (diskmgmt.msc)
Start the disk management utility in one of the following ways:
- Press WinR keys, type diskmgmt.msc into Run window and press Enter.
- In Windows 10, right-click on the “Start” button and select “Disk Management”.
- Go to Control Panel. Administrative Tools. Computer Management. Disk Management.
In the disk management window, pay attention to whether the flash drive appears and disappears when it is connected and disconnected from the computer.
Ideal. if the computer sees the connected USB flash drive and all partitions on it (usually one) in the “Good” state and with the FAT32 or NTFS file system. In this case, it is usually enough to right-click on it, select “Change drive letter or drive path” from the context menu and assign a drive letter to it.
If the section is faulty or deleted, then in the status you can see:
- RAW file system. In this case, use a separate instruction How to fix a RAW disk.
- “Not allocated.” Try right-clicking on it and, if such an item is found in the menu, select “Create Simple Volume” to create a partition and format the flash drive (this will delete the data).
- If you see an arrow next to the name (Disk and number) of the drive on the left, right-click on the name and check if the “Initialize disk” item is available.
If the disk management utility for your flash drive displays the label “Unknown” or “Not initialized” and one partition is in the “Not allocated” state, this may mean that the flash drive is damaged and you should try data recovery (more on this later in the article). Another option is also possible. you created several partitions on a USB flash drive (they can be created automatically, for example, by some programs for creating bootable flash drives). Here the material How to delete partitions on a USB flash drive can help you.
The laptop does not see the USB device. Why
Let’s see why the laptop does not see the USB device (USB flash drive, 3G modem, keyboard, mouse, tablet, etc.). To fix the problem, you can do something yourself, but somewhere you need the help of service center specialists and special equipment (soldering station, etc.).

Next, we will tell you about the main reasons for the breakdown. We are not responsible for your actions.
Check the connected device for functionality
Before looking for a breakdown in a laptop, check the device that you are trying to connect. If the laptop does not see the tablet via USB, make sure that debugging is enabled on the device (relevant for Android).
How to enable debug mode on Android
The same applies to a USB flash drive and any other device connected via USB. If this is a mouse, then make sure that it has a working cable or the Bluetooth module is fully inserted. Try to connect the equipment to another computer. if the device is detected correctly, then you should look for the cause of the malfunction in the laptop.
The main reasons why the laptop does not detect USB devices
- Incorrectly installed drivers.
- The connected device itself is not configured correctly (the same tablet or phone is not put into USB storage mode).
- Failure of the laptop south bridge.
- Lack of power supply (in the case of not connected to an outlet).
Other reasons include too many USB devices connected to the laptop. If you connect a camera or 3G modem through a hub (USB hub), because there are no free ports on the laptop, then the equipment may not have enough power. Try disconnecting unnecessary devices and connect the USB device directly to the laptop.
If the reason why does not see the USB device. the laptop itself
If the laptop does not recognize the USB flash drive, try to troubleshoot as follows:
- Turn off the laptop. Unplug, remove battery.
- Hold down the power button for a few seconds to clear any residual charge.
- Turn on the laptop and try again to connect the USB device to it.
If the system still does not detect new hardware, then it is worth checking the USB drivers of the motherboard. they may have started working incorrectly:
Click WinR. Run the command “devmgmt.msc”.
Check for unknown devices. If you see such a line, right-click and run the “Update Drivers” option. You should start an automatic search on the Internet.
If reinstalling the port does not help, try opening the properties of the connected device in the manager. In the “Power management” section, remove the checkbox “Allow shutdown to save power”.
Another point in setting up the power supply is setting a prohibition on temporarily disconnecting USB:
- Open the “Power” section in the control panel.
- Launch the power settings window for the circuit you are using.
The most serious reason why USB ports are not working is the breakdown of the south bridge of the motherboard. The south bridge is responsible for starting the laptop and the operation of peripheral devices. USB, hard disk, port for a network cable.
The microcircuit usually burns out due to misuse of USB ports. If you connected a USB flash drive from an unknown manufacturer or a device with high power consumption, did not use safe removal, then the south bridge could be damaged. It is impossible to repair it yourself, so you will have to carry the laptop to the service center.
Operating system problems
Other factors can affect the correct operation of the printing technique. These include incorrect settings, malfunctions of any elements of the operating system or even the laptop itself.
Print organization is affected by antivirus, BIOS settings and, of course, the viruses themselves.
Malware affects not only printing, but many processes in the operating system in general. First of all, the disks of a laptop or computer should be checked with an antivirus or a free utility.
In addition, the BIOS settings may “fly off”, in which, among other things, the disabling of USB ports is prescribed. This happens after an update or other action by the user. So make sure the USB controller is active.
The laptop does not see the printer
There are few ways to connect a printing device to a laptop. You can use the USB port in the old fashioned way or make a connection via a local network or via Wi-Fi. However, it happens that the printer is not detected. Many factors can lead to this. Let’s consider in a step-by-step sequence of actions that will help to troubleshoot.
The problem that the laptop does not notice the printer boils down to poor connection, improper hardware configuration, printing service, “flying” drivers, difficulties in the operating system, and some other things. The recommendations given in this review are effective in troubleshooting a faulty connection of printers from well-known manufacturers such as Epson, Samsung, HP, Canon, Brother, Xerox, Kyocera, OKI.
Immediately about a slightly outdated USB connection method, which, nevertheless, many continue to actively use. If the laptop does not see the printer via USB, then, most likely, a snag is in the wrong setup process.
But a similar situation can arise, and quite unexpectedly, when the printer communicates with a laptop via Wi-Fi or a local network. This can also be caused by various factors.
This refers to the physical integrity of all cords, as well as the condition of the laptop or computer inputs and the printer. First, inspect all connection cables for breaks, cuts, kinks, and other damage. The same must be done with all plugs.
It is also important to inspect all inputs, both on the laptop and on the printing device. Especially those that are most often used to connect with other equipment. Now you need to pay attention to the connection itself. Do not allow the cable in the connector to sit loosely or wobble. Also, absolutely avoid pulling the cords.
It may turn out that the whole thing is in the special software, which is responsible for the correct operation of the printer, that is, its drivers have simply “gone off”. This situation is most typical for Windows 7 and 8 operating systems, when the laptop does not see the connected printer.
get to the point “Management”. This can be done by right-clicking on the “Computer” shortcut. It is located in the main Start menu:
in the menu on the left, you must click “Device Manager”:
now you should find the printer by model name and visit “Properties”:
if everything is in order, it will be seen: “The device is working normally”.
If there is a problem, the message will be different. Then you have to install new driver versions.
Installing drivers manually
Another option, sometimes quite effective, is to download the driver program. Manual printer setup using it can help. Printing devices in most cases have conveniently arranged software, where the means of their detection are prescribed. In addition, when purchasing a printer, the kit may include an installation disc. Then there will be no need to download the latest driver from the manufacturer’s website.
It is important here that the old driver files should be deleted immediately before installing new ones in order to avoid software conflicts. To accomplish this, the command line is invoked by typing the Win and R keyboard shortcuts. It says printui / s. After executing the command, in the window, select the required file package in the “Drivers” section and remove it. It happens that before deleting, you need to stop the print service. Enter the command net stop spooler. When all unnecessary is removed, you need to activate the service again with the net start spooler command.
If Windows does not detect a device for printing, then the very first thing to do is to make sure that the printer is connected properly. This is true, as a rule, if printing is organized on a new computer or a newly purchased printer is connected.
If you select a USB port, first of all, check if it is the right connector. USB can be confused with an Ethernet slot, and it can even harm the printing device. When it comes to connecting to a computer, you should always use the input located on the back of the computer. Avoid front panel connectors as they are not directly connected to the motherboard.
Also check this: if the USB version is 2.0, then the input for it is black. If it’s 3.0. blue. Interface versions must be consistent. It is also highly recommended not to use USB extension cords.
Now about the Wi-Fi connection. Its signal may not be stable. And if too many consumers are connected to the network, which applies primarily to offices, it can disappear altogether. In such cases, the first thing to do is to see if the router is turned on. Then you should check the correctness of the network settings, that is, the name and access code.
Print service not started
Drivers are not the only ones responsible for managing the printer. The Windows operating system has a separate service called Print Manager. At this stage, you need to check the status of this service.
First, as in the previous section, you need to start the contents of the “Control” item. In the area that appears on the right, closer to its lower part, you need to find and click the “Services” section. All services available on the laptop or computer will be displayed. Wait for this to happen, and then select “Print Manager” from their list. We are interested in the item “Properties”:
A status window will appear, in which everything should be correct. Please note that the value of the “Startup type” field should be “Automatic”, and opposite the word “Status” should be: “Running”. If everything is correct, then with the active button “Run” it should be pressed. The print service will restart:
What if the laptop does not see the printer even after the steps above? It is worth trying to manually connect the printing device.
Through the “Start” menu, select the “Printers and Scanners” or “Printers and Faxes” section. It has the “Add” button on the right. The search for devices will start, and while it is going on, a shortcut “The printer you need is not in the list” appears at the bottom. You should select it, and then follow all the prompts and recommendations of the system.
Why the mobile device is not detected by the computer
The reasons why the laptop does not see the connected phone can be different:
- Incorrect connection of the mobile device to the computer.
- Outdated or incorrectly configured software.
- Malfunction in the USB cable, breakdown of the port of the device, mobile device or PC.
What to do if the laptop does not see the phone through the USB port
If the user connected the device to the computer correctly, but it is still not recognized, follow the steps below. If the first does not help, then go to the second, third and so on.
- Connect the phone to the laptop through a different port. usually there are several of them and all cannot fail.
- Connect your phone using a different cable. you may be using a third-party cable that is incompatible with your computer, or a faulty USB cable.
- Check if USB tethering is disabled on your phone. To do this, go to the system settings, in the “Mobile network” or “Connections” section. If tethering is enabled, disable it.
- Reboot your phone and laptop.
- If the connection problem persists, try updating the driver responsible for recognizing the USB device.
- Update the operating systems on your phone and laptop to the latest versions.
- If the problem with identifying the phone via USB appeared after updating or reinstalling the laptop operating system, try installing the original drivers from the manufacturer’s website.
- Check if the port on the phone is working correctly. To do this, connect the device to any other computer. If the connector is faulty, you will need to contact the service center. If the device is still under warranty, we advise you not to repair the port yourself.
Why the laptop does not see the phone through the USB cable, but charging is in progress
We connected the device to a PC, but it is not detected, and the battery of the device is being charged at the same time, which means that the matter is in the cable. The branded cable may be damaged. It can still charge the phone, but it is not able to provide a connection to a computer. In this case, the problem is solved only by replacing the cable. In addition, if you use not a proprietary cable, but a cheap analogue, you will be able to charge the phone, but transfer files with it will not.
How to properly connect your phone to a PC via USB
If you follow the steps below, you can avoid problems when transferring information from a mobile device to a laptop and vice versa:
- check that the phone is turned on and connect it to the computer;
- open the notification panel on the phone screen. a notification about the USB connection should appear in it;
- click on the notification and go to the USB connections tab;
- select the desired mode: photo transfer or file transfer (operating modes, as well as their names may differ depending on the device model and operating system version).
- in some models, for example, Samsung, the menu with the choice of the connection mode opens automatically.
If the phone is connected correctly, the laptop will “see” it, and it will appear in Windows Explorer.
Why the laptop does not see the phone via USB and what to do in this case?
A quick and convenient way to transfer information from your phone to your computer and vice versa is to connect via USB. But the user may face the fact that the computer, for some reason, does not detect the device connected to it. We figure out why a laptop with Windows installed does not see the phone via USB, and how to solve the problem.
How to update the driver responsible for connecting devices via USB
- Start the command prompt on the laptop by pressing the Windows R keys. The Windows key is in the bottom row and has the OS logo on it.
- Enter the devmgmt.msc command into it and press the OK button.
In the opened “Device Manager” find the necessary equipment and right-click on it.
Select the option “Update driver, and then.” Search for drivers on this computer “.
If there are several compatible devices in the opened list of drivers, select some other driver instead of the one already installed.
If necessary, after updating or rearranging the driver, restart the laptop.
If the mobile device does not appear in Device Manager, the problem may be in the laptop connector or cable.
Other ways to connect your phone to your laptop
If all of the above steps did not help, or you found out that there is a malfunction in one of the devices, and you need to transfer the data immediately, there is another option. Use services that allow you to transfer data over the Internet, for example, cloud storage Yandex.Disk, Google Drive, Dropbox, OneDrive, Cloud and others. With their help, you can quickly transfer files from phone to laptop and vice versa, without using USB.
Now you know why the laptop does not see files on the phone via the USB cable and you can try to fix this problem yourself.
Council number 3
What if my computer can’t see USB? Although very rare, it still happens that the ability to read data from USB devices is disabled in the BIOS. Most often, this is done in online stores and similar establishments so that people, using their media, do not infect computers with viruses. If we are talking about a home PC, you should go into the BIOS, and then check the box allowing the motherboard to enable USB devices.
Tip number 2
Sometimes the system immediately detects a new data storage device, but displays a message that the device is not recognized and refuses to read the information. Most often, the problem lies, again, in insufficient power supply and is solved by connecting the media to a different port. However, in some cases there is a need to update the drivers. The easiest and most convenient way to do this is using specialized programs (say, Everest). It will help you find out the name of your board, and then download the corresponding drivers from the manufacturers’ official websites.
It is also possible that the problem occurred due to the fact that Windows assigned the new device an already used volume label (letter). This is corrected using the control panel tools (right-click on the “My Computer” shortcut, in the menu that appears, select the “Control” item). On the right you will see the “Storage” tab, and in it. “Disk Management”. It remains only to find the label of our device, press the right mouse button and select the “Path to disk” item (“Change drive letter”). In the window that opens, enter a new symbol. After doing this, the problem can be resolved.
Tip # 4
If the computer does not see the information on your drive via USB, this may be due to the presence of malicious virus programs on the PC itself or the attached device. Here the solution is obvious: you should download a reliable powerful antivirus and conduct a full scan of both the computer itself and the drive.
What to do if the computer does not see the USB device?
What if my computer can’t see USB? First of all, you need to make sure that the device itself that you need to connect is not damaged. You can check this very simply: if everything is normal when you connect it to another computer, then the device itself is working properly. Also, when connecting it to your PC, pay attention to whether the light (LED) comes on. If the computer does not see the phone, the USB ports and cable may be fully functional, but you need to check the settings of the device itself and confirm the ability to exchange data between it and the computer (if this option is disabled, the device will not appear on your computer). This also applies to tablet PCs, smartphones, MP3 players and similar gadgets.

What if the computer does not see USB in this situation? Simply reconnect the device to one of the ports on the back.

Finally, you might just want to format the drive. This can be done if it is displayed in the list of connected devices. However, when formatting, all data saved on it will be permanently deleted.
