  1. Enable USB legacy features in your BIOS

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR.
    1. Disable searching Windows Update for device drivers
    1. Click Start, right-click Computer, and then click Properties.
    2. In the Tasks list, click Advanced System Settings.
    3. On the System Properties dialog box, click the Hardware tab, and then click Windows Update Driver Settings.
    4. Select Never check for drivers when I connect a device.
    5. Click OK twice, and then close the System dialog box.

     

  3. “complete” USB driver renewal and see if that helps.

    Create a file with NOTEPAD containing the following lines and save it as FIX.REG
    ————————– cut after this line ——————————–
    REGEDIT4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

    “DEVMGR_SHOW_NONPRESENT_DEVICES”=”1”
    ————————– cut before this line ——————————–

    Double click on FIX.REG and say yes to the Merge Into Registry question.

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Disk Drives that you know are not present.
    Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn’t uninstall, ignore it and move to the next one.
    If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

    When this is done, reboot TWICE.

Reconnect the USB devices and see if they’re recognized properly.
