Enter "regedit" in the "Run" dialog box, press Enter, open the Registry Editor, expand the following branch [HKEY_LOCAL_MACHINE\SYSTEM\CurrentCntrolSet\Services\USBSTOR], and find the name "Start" in the right pane. The DWORD value, double-click, in the edit dialog box that pops up, modify its numeric data to a hexadecimal value of "4". Click the "OK" button and close the Registry Editor, restart your computer for the settings to take effect.

Tip: The “Start” button is the working switch of the USB device. The default setting is “3” for manual, “2” for automatic, and “4” for disabled.
