    Regedit. Go to:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR
    Change ErrorControl key value to 3 Hex
    Find C:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_20f76ee4fbfc4cb8
    (or something similar)
    Copy usb.inf and usb.pnf to C:\Windows\INF (overwrite existing files)
    If usb.inf is prohibited, just proceed without copying.
    Unplug all USB connections.
    Turn off computer completely for at least 15 seconds.
    Restart.
    Add all USB connections again.
