Disable USB Storage Using Regedit

There is a simple registry change that will keep the USB storage drivers from starting when the system boots. Keeps people from walking up to a PC and copying data off with a USB storage or pendrive, but allows you to keep your scanner, keyboard, and mouse in working 

state.HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor

Notice the value ‘Start‘

Switch this value to 4, and USB storage devices are disabled.
Switch this value to 3, and USB storage devices are enabled
Another procedure is :copy these text in to the notepad then save it as a .bat extension(Like: example.bat)

@ECHO off
cls
:start
ECHO Press: 1 - to Enable USB storage device.
ECHO Press: 0 - to Disable USB storage device.
