Stop User To use such as USB Storage Devise, need to Create 
New Custom Group policy in Group policy Editor , Normally 
All USB Storage Device are using Windows Driver's System 
file “USBSTOR.SYS”, we can also block it through to stop 
using this file..

Log in as administrator.  Disable USB ports in device
manager.  Enable GPO to restrict access to Control Panel to
the user group you do not want to access it.  Restricting
Control Panel is the broadest restriction.  Any alternate
method to access device manager is inherent.  Easier to
drill down to policy to undo policy.  Key thing is not to
modify default AD Policy.  Create a custom policy at the root.
