The computer does not see the tablet via USB

Reboot both devices

Perhaps “software garbage” interferes with the PC system or something did not work on the tablet. after restarting, it will be possible to establish a connection.

Broken wire or broken connector in the cord

Do not pull on the cord. this will really damage the connector (leg). Carefully inspect the wire for kinks and micro-damage. Replace cable and try again.

It will not be difficult to buy a new cord, and it is inexpensive. It is worth paying attention to the connector, there are three types:

  • Mini USB (Obsolete)
  • Micro USB
  • Type-C (most modern)

If you do not want to spend money, re-solder the old one.

Tablet does not appear in the device list

If, after you connected to the computer, the tablet began to charge, but your device is not in the list of devices on the PC, then the problem lies in the software itself, which is installed on the tablet. You can try to solve this problem partially. You just need to restart the tablet, after which it will be displayed in the list of connected devices and, if necessary, download and install additional drivers will begin.

Computer USB connector problem

The problem may be a broken connector on the computer. In this case, connect a USB flash drive or other device to the same connector. If it does not help, then try connecting the tablet to a different connector. If this is not possible, then contact the service center, where the USB connector will be replaced or repaired.

Information exchange module burned out

Using the information exchange module (multi-bit buses), the PC transmits data to the processor, which, in turn, to the connected gadget and vice versa. If it burns out, then you cannot do without the help of the service center specialists.

Setting up a tablet to connect to a computer

If everything is in order with the drivers, but the tablet still does not connect, then the Android device itself may have been incorrectly configured.

You need to pay attention to the fact that different models of tablets can be connected to the computer as different devices:

  • USB stick or USB large storage. We recommend that you select this connection option to perform different actions between your computer and tablet. Working in this mode will allow you to manage files on your tablet from your computer, freely exchange all types of files.
  • Media device (MPT). Connecting through this mode, you can transfer media files only to a computer, while it is prohibited to manage files on the tablet from the computer.
  • The camera mode is practically no different from the previous one.
  • Some models also have a charging-only mode. When this mode is connected, almost all functions of the tablet are turned off in order to carry out the fastest charging.

Sometimes the firmware of the tablet can work in such a way that in some modes the tablet will not be connected to the PC, but only will be charged. Check the connection with different modes to solve this problem.
You can switch between modes in this way:

  • Connect your tablet to your computer.
  • Tap the screen a few times or expand the top left panel to display the USB icon. The process of opening this function directly depends on your device model and its firmware.
  • You will have a button that will show in which mode the tablet is currently connected. You need to click on this button and change the settings there.
  • It is best to check the box next to “USB large storage”, which in some models is referred to as a USB storage device. In this mode, you will have complete control over the device. But if the mode does not work, try switching to another, then back again. Perform various manipulations to check the connection.
  • Don’t forget to click the Enable USB Storage button as well. A tab with this button should be displayed on the screen when the tablet is connected to the computer, if everything is working properly.

    Tablet does not appear in the device list

    If, after you connected to the computer, the tablet began to charge, but your device is not in the list of devices on the PC, then the problem lies in the software itself, which is installed on the tablet. You can try to solve this problem partially. You just need to restart the tablet, after which it will be highlighted in the list of connected devices and, if necessary, the download and installation of additional drivers will begin.

    Other

    If none of the above methods helped you, then you can take several actions that will help in such critical cases. You can return your tablet to factory settings. This will delete all custom settings and delete all files. If this method did not help, then you need to go to the very last option. flashing the device. You may have caught some kind of virus or a system crash that did not resolve when returning to factory settings.

    You can return the tablet to factory settings in this way:

    Select the item “Restore and reset” and click “Reset settings”.

    After performing the reset, the tablet will reboot and you can use it.

    If you are an inexperienced user, then do not try to flash the tablet yourself, as you can get a “brick”, it is better to contact the service center.

    Do everything very carefully, it is better to ask someone else to help you if you do not understand such devices, as you can only make things worse. Also, do not try to force the wire into the connectors, as you may be doing something wrong, and this will lead to damage.

    Sooner or later, each of us has a need to transfer content from a tablet computer to a personal one: work files, tablets, presentations, photos, videos and much more. And what is our disappointment if the computer does not see the tablet. Of course, you should make sure that the device is not turned off and charged.

    Two ways to connect your tablet to your computer

    How to fill a new tablet with media content. music, movies, games? You can, of course, download everything you need directly from the Internet. But it’s faster and more convenient to transfer from another device. Let’s figure out how to connect a tablet to a computer so that you can safely move the files you need.

    USB debugging

    • Go to the “Settings” section on the tablet.
    • Find the item “For Developers”. If it is not there, go to the “All settings” tab, then click “About the tablet”. Find the “Build number” field and click on it 7 times. If everything is done correctly, the message “You have become a developer!” Will appear, and the necessary item will appear in the tablet settings.
    • Activate, by checking the box, the “Debugging via USB” mode.

    These actions are designed to eliminate possible conflicts between PC and tablet, which are related to the specifics of the Android OS.

    Periphery

    Since Windows 8.1 natively (by default) supports Bluetooth, you are unlikely to have problems connecting any external keyboard / mouse as an alternative input device.

    If you prefer the more traditional USB-based options (with or without cable), you should first check if your tablet has a full-sized USB port. Some devices only have micro-USB, so you’ll need a standard USB adapter again to connect a mouse and / or keyboard.

    You may be wondering: How to open or hide hidden folders in Windows 10

    One major inconvenience is the fact that most Windows tablets have only one USB port. If you want to connect several external devices at the same time. an additional hard drive, flash drive, printer, camera, and so on, you will need a USB hub (hub).

    In addition, we advise you to choose a hub model with its own power source. so-called low-voltage USB versions are used in mass-produced tablets, i.e. ports that cannot simultaneously power a mouse, keyboard, external hard drive, etc.

    Well, since we are talking about operating a device with Windows, then you should not have any problems installing compatible peripheral devices of any kind, type and caliber. after connecting the device, the operating system itself will detect the necessary drivers for it and install them without your intervention (plug and play).

    Disconnection

    To disconnect the tablet from the PC, follow these steps:

    • Click on the USB icon on your tablet.
    • Select “Disable”.
    • Find the removable disk icon in the Windows system tray.
    • Left-click on it and select “Safely Remove”.

    Now you can safely pull out the USB cable without worrying about the transferred data being lost.

    If you do not have a USB cable or do not want to use it, you can connect via a Wi-Fi network. Both devices must be connected to the same network.

    On the tablet, you must first install the OnAir application, and on the PC. any file manager, for example, Total Commander.

    • Run the application on the tablet and select the FTP mode.
    • Enter any data for connection: server address, account name, password.
    • Open Total Commander on your computer and create a new FTP connection, specifying the same data as in the OnAir application.

    Another connection option is via Bluetooth technology. To do this, you need to configure Bluetooth on the laptop, enable the corresponding function on the tablet and pair the devices.

    How to connect a tablet to a computer via USB

    The scheme of actions is quite simple and there should not be any special difficulties. After you connect the tablet, a USB picture and a notification “USB device connected” will appear on its monitor.

    Click Start → My Computer on your computer. There you will find a new device, which will be your tablet. If the tablet does not open in the computer, then you need to pull the USB icon down on the tablet itself. A new menu will open in front of you, in which you need to click on “USB device connected” and select “Enable USB. storage”. After that, on the computer, you can already open the tablet on your own, or wait a few seconds before activating autorun.

    USB connection

    Connect your tablet and computer with a cable. Usually this is a microUSB-USB or miniUSB-USB cable that comes with your device. After connecting, Windows will immediately give you a message about the detected new device, and will offer to install the driver. You can safely ignore this message by simply clicking the “Cancel” button. Now take your tablet, in the lower right corner, click on the USB connection icon and click on “USB connection established.” In the new window that appears, click on the “Enable USB storage” button. The system will immediately issue a warning about the possible stop of some applications, which click “OK”.

    After that, the internal memory of the tablet, including the external microSD card, will be available in Windows Explorer as external drives. Now you can perform any actions with tablet files. edit, delete, copy, archive and much more, just like you do with files on your computer.

    The phone does not connect via USB to the computer, but only charges

    If no notifications about a USB connection to a computer appear, then here is a step-by-step description of possible actions:

    • Try connecting to a different USB port. Better if it is USB 2.0 (the ones that are not blue) on the back. On a laptop, respectively, just USB 2.0, if available.
    • If you have compatible USB cables from other devices at home, try connecting with them. A problem with the cable can also be the cause of the described situation.
    • Are there any problems with the jack on the phone itself? Did it change and did it fall into the water. This can also be the reason and the solution here is a replacement (I will outline alternative options at the end of the article).
    • Check if the phone is connected via USB to another computer. If not, then the problem is in the phone or cable (or the Android settings were poorly checked). If so, the problem is on your computer. Are flash drives connected to it? If not, we first try to go to the Control Panel. Troubleshooting. Device Settings (to try to fix the problem automatically). At the same time, it is worth trying to disable energy saving in the device manager for Generic USB Hub.

    If nothing from the list helps to solve the problem, then describe the situation, what was done and how your Android device behaves when USB connected in the comments, I will try to help.

    Note: The latest versions of Android are by default connected via USB to the computer in charge-only mode. Check the notifications for the availability of the USB operating mode selection, if you are faced with this (click on the Charge via USB item, select another option).

    Why Android phone is not visible via USB

    I think it’s worth starting with answering the question: has the computer always not seen your phone, or has everything worked normally before? The phone stopped connecting after actions with itself, with a computer, or without any action at all. the answers to these questions will help you quickly find out what exactly is the matter.

    First of all, I note that if you recently purchased a new Android device and the computer on Windows XP does not see it (at the same time, an old Android phone can easily connect as a USB flash drive), then you should either update the operating system to one of the currently supported ones, or install the MTP (Media Transfer Protocol) for Windows XP. You can download MTP for XP from the official Microsoft website here: https://www.microsoft.com. After installing and restarting your computer, your phone or tablet should be determined.

    Now let’s move on to the situation when the phone is not visible via USB in Windows 7, 8.1 and Windows 10. I will describe the steps in relation to Android 5, but for Android 4.4 they are the same.

    Note: for devices that are locked with a pattern or password, you need to unlock the phone or tablet connected to the computer in order to see the files and folders on it.

    Make sure that the phone itself, when connected via USB, says that it is connected, and not only for charging. You can see this by the USB icon in the notification area, or by opening the notification area in Android, where it should be written which device the phone is connected to.

    This is usually a storage device, but can be a Camera (PTP) or USB modem. In the latter case, you will not see your phone in the explorer and you should, by clicking on the notification about using a USB modem, turn it off (you can also do this in Settings. Wireless networks. ).

    If the phone is connected as a camera, then by clicking on the corresponding notification, you can enable MTP mode for file transfer.

    On older versions of Android, there are more USB connection modes and USB Mass Storage will be optimal for most use cases. You can also switch to this mode by clicking on the USB connection message in the notification area.

    Computer does not see Android smartphone via USB

    The computer does not see the Android smartphone via USB. If you are faced with the fact that the phone does not connect via USB, that is, the computer does not see it, in this guide you will find all the options known to the author for what is happening, as well as ways to fix the problem.

    The steps below refer to Android phones as the most common with us. However, to the same extent, they can be used for tablets on Android, and some points can help to understand and with devices on other OS.

    Additional Information

    If you come to the conclusion that the reason for the problems when connecting the phone is its physical problems (socket, something else) or you just do not want to understand the reasons for a long time, then you can transfer files from and to the phone in other ways:

    • Synchronization via Google Drive cloud storage. OneDrive. Dropbox. Yandex Disk.
    • Using programs like AirDroid (convenient and simple for novice users).
    • Create an FTP server on your phone or connect it as a network drive in Windows.

    The computer does not see the tablet via USB, but it is charging. how to fix the problem

    Mobile devices connected via a USB cable to a PC are often automatically detected by the operating system and further work with them (synchronization, file transfer) does not require additional actions. However, sometimes such a nuisance happens when the computer does not see the Android tablet connected via USB, but it is charging. Consider the causes of the problem and how to fix it.

    Hardware causes and their elimination

    This type of malfunction includes a variety of damage to the connection components:

  • Damage to the USB socket on the computer. The cable connection points are under heavy stress due to constant use, therefore they often fail. You should try to plug the cable into a different connector to diagnose the problem.
  • Damage to the Micro-USB or USB Type-C input on the tablet. Perhaps moisture has penetrated there and the contacts have oxidized, or the device has been in places of increased dust and dirt has clogged there. Inspection of the connector should be carried out and, if defects are detected, contact the master.
  • Another rather strange solution to the fact that the PC does not see the Android tablet via USB, but charging is in progress, will be the removal and installation of the battery. Many users note that the problem is resolved after briefly disconnecting the battery from the tablet contacts and reinstalling it, then starting the OS.
  • Diagnosis of hardware problems consists in the alternate replacement of components and the use of alternative connection options.

    Programmatic reasons and their solution

    Problems caused by the software environment can occur on both the tablet and the computer. Let’s dwell on each of them in detail.

    Change tablet settings

    The reason for the incorrect connection may be incorrect settings on the machine. To fix the problem, you should:

    • Go to the “Memory” section.
    • Click on the three dots at the top of the screen and select “USB-connection to a computer”.
    • In the window that opens, you need to check the box opposite the line “USB storage”. If there is a mark next to the item “USB as a modem”, you need to remove it.

    The corresponding settings must also be made on the computer:

    • Enable the operating system update service to get the latest software versions.
    • Activate Connected Device Discovery.
    • Users of outdated Windows XP should install a protocol called MTP into the system.

    Custom firmware

    Installing the modified firmware may cause a problem with connecting the device via the USB input to the PC. The solution is similar to what applies to Windows. reinstalling the firmware to the standard version.

    Reinstalling drivers for your tablet

    The failure can occur in the drivers that were installed in Windows for the mobile device. To fix the problem, you must:

    Expand the item “Portable devices”. Select the connected tablet and right-click on it, then click on the “Properties” line.

    Select the “Driver” tab, click the “Remove” button.

  • Disconnect the tablet from the USB input and reconnect to the PC.
  • Wait for the system to reinstall the required software.
  • There are times when the system fails to detect the tablet model and load the required driver. The solution will be to independently search for software and install it manually.

    Reinstalling USB Port Drivers

    Sometimes the computer does not see the Android tablet connected via USB due to a driver failure. The solution is to re-install the USB software using the driver disc that came with the motherboard or by downloading the necessary files from the Internet.

    It is also useful to check the power saving mode on laptops, which can limit the power supply of USB ports. To do this, you should:

      Open the control panel and go to the “Power supply” section.

  • Click the link “Power plan settings” opposite the active profile.
  • Click the line “Change advanced power settings”.
  • In the window that opens, scroll down the list and expand the “USB Settings” item.
  • Set the value to the “Disabled” position to prevent the system from temporarily interrupting power to the ports to conserve battery power. Such an add-on should also be installed in relation to the mains supply option.
  • Press the “OK” or “Apply” button to save the changes.
  • How to fix if the computer does not see the phone connected via USB. additional methods

    If your phone does not connect via USB to a data-capable computer, but only charges, try the following methods to fix the problem.

    Checking phone operation (MTP device) in device manager

    • Open Device Manager on your Windows 10, 8.1, or Windows 7 computer while your phone is connected. To open Device Manager, you can press the WindowsR keys on your keyboard, type devmgmt.msc, and press Enter. Windows is the OS logo key.
    • See if there is a device in the device manager named MTP (MTP Device, MTP Device) or the name of your phone (may be in the “Portable Devices” section).
    • If there is, double click on it, go to the Driver tab, click Update driver. Search for drivers on this computer. Select from a list of available drivers on your computer and see the list. If it has more than one compatible device, try to select a different driver than the one currently installed, usually you need to select “USB MTP device”.
    • If no new devices appear in the manager when disconnecting and connecting the phone via USB, this is another argument in favor of problems with the cable, connector on the phone or computer.

    Among other things, if the issue under consideration occurs, please note the following points:

    If none of the options helps to solve the problem, and the computer still does not see your Android smartphone, describe the situation in the comments: what was done, after which the problem appeared, how does your device behave when connected via USB, has the cable been checked with another phone, and the problematic device is on another computer. I will try to help.

    The computer does not see the phone via USB. why and how to fix it

    If you are faced with the fact that the phone does not connect via USB, that is, the computer does not see it to transfer files, but only charging occurs, while the connection sound is played, this manual provides details on how to fix this and enable the ability to view content phone memory when connected via USB cable.

    The steps below are suitable for both latest and previous Android phones in case the smartphone is not visible after connecting via USB on a computer with Windows 10, 8.1, Windows 7 and XP or Mac OS.

    Why Android phone is not visible on the computer via USB and only charging takes place. simple reasons and solutions

    Before proceeding with additional methods for solving the problem when the phone is not visible through the USB connection, I recommend paying attention to the following simple points: very often the reason is one of the following:

    • If you took a USB connection cable from a non-original cheap charging or bundled with another device (for example, to charge wireless headphones or another device that is not intended for receiving and transmitting data), then this may be the reason: not all cables can transmit data, there are no corresponding contacts, and outwardly it is not noticeable. The solution is a working cable with guaranteed data transfer capability.
    • If you are faced with the fact that when you connect a smartphone to a computer, it is not visible, and recently the phone was repaired and something related to the board or connector was repaired, it is highly likely that the repair caused the problem: very often the connectors are soldered so that after that only charging works properly. The solution is just to redo.
    • If you have Mac OS, just install Android File Transfer app for data transfer capability, official website: https://www.Android.com/filetransfer/
    • If you still have Windows XP, install the MTP (Media Transfer Protocol) driver. https://www.microsoft.com/en-in/download/details.aspx?ID=19153

    Additionally, keep in mind that connecting even with a working cable through a USB hub (USB port splitter) to a faulty USB connector on a computer or laptop, and sometimes to the front panel of a PC may cause the problem under consideration. Try a direct connection to USB, another connector, the back of the PC, if connected to a USB 3.0 connector (usually blue). check if the problem persists when connecting to USB 2.0.

    And the last simple point: after connecting the phone to the computer, in order for it to appear in the explorer with the ability to view photos, videos and other files, you need:

    • Unlock the phone when connected, if it is locked. you will not be able to access data on locked modern Android phones.
    • In the notification area, click on the USB connection notification (by default, most phones are connected only for charging). If the notification does not appear, more precisely, it does not say that this is a USB connection, but only a text about charging, then from the “point of view” of the phone, the connection does not serve for data transfer (wrong cable, damaged cable, connector on the phone or computer) Below are screenshots with the appearance of the notification on pure Android 9 and 8, on Samsung Galaxy and on Android 6-7.
    • Select MTP file transfer mode for USB connection. On older versions of Android, there may also be an item for connecting as USB Mass Storage, it will also work, and it may work even better.

    If the listed methods did not help, let’s move on to more complex fixes.

    Additional Information

    If you come to the conclusion that the reason for the problems when connecting the phone is its physical problems (socket, something else) or you just do not want to understand the reasons for a long time, then you can transfer files from and to the phone in other ways:

    • If you have Windows 10, use your phone’s built-in app (photo transfer only), if your Samsung phone uses Samsung Flow app.
    • Synchronization via cloud storage Google Drive, OneDrive, Dropbox, Yandex Disk.
    • Using programs like AirDroid (convenient and simple for novice users).
    • Create an FTP server on your phone or connect it as a network drive in Windows.

    Hello, the Homtom ht16 phone has been in use for 2 months. It does not turn on, I thought the battery sat down, it does not react to charging. I charged the frog battery, zero sense. Does not turn on for charging does not react, I connect silence to the PC in the manager. I decided to cheer up through the sp flash tool without a battery with the volume down button pressed down to silence. I tried to restore bricks, but on the PC it does not react at all with or without a battery. When charging, it heats up in the processor area, is it a short circuit? he just lay there. I don’t know where to dig next

    Hello.
    I also don’t presume to guess. You can try to power it directly (just watch the voltage / current carefully) and see if it turns on like this.

    Good afternoon, tell me please.
    Can’t connect to laptop.
    I plug it in, it’s charging, nothing else, even the top of the phone does not show that it is charging. I did the debugging, I changed the cable. For a split second, this window appeared with a choice of data transfer and that’s it. I did not understand where it disappeared. No more appeared, no matter what I did.

    Hello.
    Could it be a phone jack? See that there is no dirt there and use the same cable where the window appeared.

    If the computer does not see the phone, but the photo is being transferred from the phone to the computer. There is no telephone in the connected devices in the display. How to solve this problem?

    I do not quite understand But how exactly is the transfer going in this case?

    The phone was bought in China. If you go into the documents and select the desired removable disk, then the disk is designated as a CD-drive (F 🙂 HiSuite. I open it, there is a folder with a PDF document, the document is called OPEN SOURCE SOFTWARE NOTICE, and three files: autoran, HiSuite, and with Chinese characters. If you open the last file, the menu for installing HiSuite on-line appears. And the photos are somehow strangely transmitted. OneDrive opens automatically even though I’m not using it. And the menu for importing images appears immediately. It turns out that if you select the transfer of photos, the disk is visible, and if you select the transfer of files, the disk is not visible. Initially, there was no such problem. Maybe due to updates on the laptop this happened.

    Hm strange. And other disks during the “file transfer” except F does not appear?

Unknown Device (Device Descriptor Request Failed). There is a suspicion that this is after charging from an iPhone charger. I rolled the phone back to factory settings. Then I replaced the phone’s USB cable, but the situation did not change. I understand that this is some kind of hardware problem. Tell me what else can be replaced without any problems and costs?

    Hello.
    Unfortunately, now it is difficult for me to give any recommendation, I explain:
    1. When I started reading the comment I thought: there is clearly something with the connector on the phone (dirt, dust, damaged contacts).
    2. When I read to “replaced the USB cable of the phone”. I realized that it is useless to guess now: the point is that, without exaggeration, half of the repairmen solder these connectors in such a way that after that the phone can only be charged. And there is a great chance that you too.

    In general, the correct solution is to contact someone who understands exactly and it is with this problem to address, not just ask to replace the connector.

    Good afternoon, the article did not help, but I think the problem is still on this topic. Budget Smart OPPO A-12. When connected to a PC, be it a USB or FTP server (via Wi-Fi), the PC sees the device, but I cannot send large files (movies) to the smartphone. I can’t say for sure the minimum size of a file that can be transferred, but it transfers documents and music without problems. Nothing happens with large files, it does not knock out any error either on a PC or on a smartphone, there is more than enough memory on a smart phone to download a file, I also tried the USB 2.0 and 3.0 ports. Tell me what could be the solution to this problem?

    Antivirus programs are blocking third-party connections. You need to disconnect them and try to reconnect the PC to the tablet.

    Hardware and software

    • Broken USB PC connector. This can happen if the computer has been in use for a long time. To check the connector, you need to connect other devices to the device. A flash drive, keyboard, computer mouse, camera or phone will do. Many computers are manufactured with multiple slots. If one is broken, the other is worth trying. over, the worn out module must be replaced. You can do this yourself, but it is better to have the equipment serviced. Especially if the warranty period has not expired. Then the masters will carry out free repairs and give a guarantee for their services.
    • Disconnected connector or broken wire. If the cord is pulled continuously, it may break off. The leg or connector will be damaged. It is necessary to assess the condition of the part. It is important that there are no creases and microdamages on it. If they are, the cable must be replaced. It is not difficult to buy a new cord, especially since it is cheap. There are 3 types of connectors: mini USB, micro USB, Type-C. The first kind is obsolete and rarely needed. The latter is considered the most modern model. It is often bought for Ultrabooks.

    Important! You can also re-solder the old one. But this should only be done if the person is confident in their experience. Otherwise, the internal parts of the PC may be damaged.

    USB options NOT showing in android when connected to PC but phone charges

    There are also software reasons why PC stopped seeing Android or IOS system:

    • the device is not updated. you need to go to the manufacturer’s official website and see if OS updates have been released;
    • non-native firmware installed. you need to install the official software.

    Checking your tablet settings

    In many tablets, the connection goes through the settings. When you try to connect, a notification will appear. It needs to be confirmed. If this does not help, you should go to the settings and select the type of connection.

    What to do if the computer does not see the tablet via USB

    Technical experts advise you to follow a clear algorithm of actions. This will help you find the problem as quickly as possible.

    Checking and replacing the cable

    If the cable is OK, the tablet will start charging via the PC. If there is no charging, you need to change the cable to a new one.

    Possible reasons

    The problem can arise for various reasons. If the PC stops seeing the tablet, it’s worth checking all the details. Perhaps the device settings are out of order or the internal elements are broken.

    What to do if the tablet does not see the computer

    The problem is that the tablet does not see the computer, which is quite common. over, such a failure can befall the user both at the first connection to the PC, and after a while. Often the tablet becomes inaccessible after flashing. Let’s look at all the reasons in ascending order.

    Asking why the computer does not see the device, first of all, you need to check the tablet itself for permission to access it from third-party devices. This problem is most often encountered by people who first encountered newfangled devices.

    This kind of problem is very easy to solve. You just need to turn on the device like a USB stick. The only catch is that different devices do it differently. In modern models, when connected to a PC, the “Enable USB storage” button will be displayed. If such a button does not appear, then you need to go to the device parameters and find the memory settings. It is in this menu that the button is hidden, which turns on the device as a drive.

    If the PC does not see the tablet through the lanyard in this case, try turning on the “Debugging via USB” mode in the “For Developers” settings. This will give a 95% positive result, but still, if it did not work out and so, then the situation is much more difficult.

    Technical breakdowns or controller mismatch

    It often happens that the cord is simply out of order, which is the reason why the PC does not see the device. If you have a model with a USB, mini- or microUSB connector, then an old cable from a camera or any other device will do. Worse, if it’s the first models of Samsung or iPad, where the cords are specific. Then you need to look for a friend, the owner of the same cord, to check the relevance of this reason. In addition to the wire, the USB controller itself can also fail directly in the model itself.

    Another reason may be the mismatch of controllers between the device and the computer. This is especially common when a modern laptop does not see the device. The fact is that modern laptops are equipped with a new generation of USB 3.0, which is why the tablet may not be recognized. It is easy to distinguish them. they are blue inside, and USB 2.0. white. You need to try to connect to the old connector. True, modern models are fully compatible with new controllers and sometimes have such ports themselves.

    Drivers

    It often happens that the PC does not see the tablet, especially after the firmware, due to drivers or their mismatch. The operating system itself does not always have a driver for the required hub, so it replaces it with a compatible one. In such cases, it is not determined at all or is determined every other time.

    Ideally, you need to download drivers specifically for your model. If you are the lucky owner of a tablet that was sold in a white package without decals, then the best option would be to download the Driver Pack Solution program, which automatically detects missing drivers on devices and prompts you to install them. At least it won’t be superfluous.

    These are the main reasons why the PC does not see the tablet through the cord, which you can handle on your own. If the above actions did not lead to a result, then the problem is already hardware. To eliminate it, you will need special equipment and certain knowledge in microelectronics.
