    Set the permissions on the usbstor.ini and pnf in the C:\Windows\inf folder.

    Also set the permissions on the usbstor.sys in C:\Windows\System32\drivers

    Set it to deny read for the users that you do not want to use USB drives. This can be done via group policy as well.

    Restrict access for installation of new USB storage devices by editing this file

    %SystemRoot%\Inf\Usbstor.pnf
    %SystemRoot%\Inf\Usbstor.inf
    Restrict access by disabling the driver:

    [HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \UsbStor]
    Start = 4
