My HUAWEI computer cannot identify USB devices

Problem

The HUAWEI computer cannot identify USB devices.

Cause

  • Third-party antivirus or manager software blocks USB devices.
  • The USB serial port driver is abnormal or unstable.
  • The USB port is disabled.
  • The USB is selectively paused, and the settings are abnormal.
  • The USB connection is faulty.
  • The format of the USB device is incompatible with the Windows system.
  • The partition file of the drive where the USB device is located is damaged.

Solution

Connect the USB device to another computer and check whether the device can be identified and used. If not, the USB device is faulty. Contact the USB device vendor. If yes, perform the following steps to locate the fault.

  1. Uninstall third-party antivirus or manager software, restore the firewall, and restart your computer.
    • Uninstall any third-party antivirus or manager software:
      1. Enter appwiz.cpl in the search bar and open it.

      2. Right-click on the antivirus or manager software you wish to uninstall, and click Uninstall/Change.

    • Restore the firewall: Enter Control Panel in the search box and open it, go to System and Security > Windows Defender Firewall > Restore defaults, and restore the firewall as prompted.
  2. Uninstall the USB Mass Storage Device from the computer, and then remove and re-insert the USB device again.
    • Right-click the Windows icon and open Device Manager. Click to expand Universal Serial Bus controllers, right-click USB Mass Storage Device, and select Uninstall from the shortcut menu.

    • You can also uninstall and reinstall the serial port driver as follows: Open Device Manager, click to expand Universal Serial Bus controllers, right-click USB root hub (usb3.0), and choose Uninstall from the shortcut menu. Then, right-click Universal Serial Bus controller again, and click Scan to detect hardware changes. Disconnect the power supply and all external devices. Press and hold the Power button for 10 seconds, restart the computer, and reconnect the external device.
  3. Check the USB port settings on the computer's BIOS settings screen.
    1. During startup or restart, press and hold or press F2 consecutively to enter the BIOS settings screen. Check whether the USB Port Enable item exists.
       
      • If not, skip this step.
      • If USB Port Enable is enabled, skip this step.
      • If USB Port Enable is disabled, enable it.

    2. On the BIOS settings screen, press F9 to restore the BIOS Default Settings, click OK, and press F10 to save the settings. The USB port is enabled by default in the initial BIOS settings.
  4. Set USB selective suspend setting to Disabled. To do this, perform the following:
    1. Enter Control Panel in the search box on the taskbar and open it, choose to view by Small icons, and select Power Options.

    2. Click Change plan settings.

    3. Click Change advanced power settings.

    4. Expand USB settings > USB selective suspend setting, and set both On battery and Plugged in to Disabled. Then, click OK.

      The USB selective suspend setting option is unavailable on certain models. This is because the function is hidden by default on Intel 11th Gen or later processors. You'll need to modify the registry to add the setting. The detailed process is described as follows:

      1. Press Win+R to open the Run window, enter regedit, and press Enter.
      2. Find Attributes under Computer \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\2a737441-1930-4402-8d77-b2bebba308a3\48e6b7a6-50f5-4782-a5d4-53bb8f07e226.

      3. If Attributes does not exist, right-click the folder on the left pane to create a DWORD(32) value named Attributes. Double-click Attributes and change its value to 2.

      4. Go to Control Panel > Power Options > Change plan settings > Change advanced power settings > USB settings > USB selective suspend setting, and set both On battery and Plugged in to Disabled. Then, click OK.
  5. Check the connection status of the USB device.
    1. The port size of different USB devices may be different, and they may not be fully connected to the computer. In this case, you can pull out the USB device slightly to fully connect it to the computer. You can try this method for a USB device that has a size deviation.
    2. The computer may not respond if you have incorrectly plugged the external device into the computer. To resolve this, plug the device into the computer again and check whether this issue has been resolved. Alternatively, plug the device to another USB port of the computer. The sizes of some USB ports on external devices are not standard and may not fit into the USB port on your computer.
    3. If you are using a portable hard disk, connect the docking station to a power cable, and then connect the portable hard disk to the docking station to check whether the issue is caused by power supply problems.
    4. The USB device may have been permanently damaged by extreme environments, errors during hot swap operations, or read/write operations that exceed the USB device's service life. As a result, the stability of the USB device may have been affected, and the computer may not be able to identify it. In this case, you are advised to use a new USB device.
  6. Verify if the file or directory is damaged and repair it.
    1. Enter File Explorer in the search box on the taskbar and open it. Double-click the drive letter. A message is displayed, indicating that the file or directory is damaged. Click OK.
    2. Enter cmd in the search box on the taskbar, right-click Command Prompt, and choose Run as administrator from the shortcut menu.
    3. Assume that the drive letter is G:. Enter the chkdsk g: /f command and press Enter. Once the check is complete, you can continue to use the hard disk.

  7. Check other settings.
    1. Right-click the USB device partition and choose Properties from the shortcut menu.
    2. Click the Tools tab and then click Check.

    3. Select the two options and click Start to proceed to the next step.
    4. After the results of the check are displayed, close the window.
    5. During the check, the system automatically repairs any repairable partition errors.

    This case is applicable when the USB device cannot be opened by double-clicking it, but the properties function is normal by right-clicking it.

  8. Format the USB device.

    Formatting a USB device will cause data loss. To prevent data loss, back up data on the device before resetting the device.

    1. Enter File Explorer in the search box on the taskbar and open it. Right-click the drive letter and select Format from the shortcut menu.
    2. Keep the default settings and then click Start to proceed to the next step.
    3. Wait until a dialog box is displayed, indicating that the formatting has been completed.

If the issue persists

If the issue persists, back up your data in advance, record your Office account, and use F10 to restore your computer to its factory settings. If the issue remains unresolved, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance. We will do our best to address your needs.
