To fix unknown USB device (device descriptor request failed), just disable the Fast Startup by following these steps: Go to the START > Type RUN in the search bar and hit ENTER. Then, run dialog box will get open, type there Control Panel and hit OK. In Control Panel, in the search box type Power options. Select the Change what the power buttons do > Change settings that are currently unavailable > Shutdown settings > Turn on fast startup (recommended).
