The new USB pen drive installation mechanism on XP machines works with two files stored in the Windows/Inf (Hidden Folder) folder: usbstor.inf and usbstor.pnf.
To disable this function, you must deny access to the "System" built-in user group for the XP machine.
However, on large networks, changing the permissions for these two files on each individual machine is a hassle. However, you can easily incorporate these permissions into your log-on script as shown below:
cd\

cd c:\windows\inf
echo|y cacls usbstor.inf /p system:n
echo|y cacls usbstor.pnf /p system:n
Now any new USB pen drives connected to the PCs will not be automatically installed. To enable access, you will have to change the n's in the script to f's.

Try This .. I hope this will work for you.
