I am a clerk of a small company.

Two weeks ago, my manager told us that a valuable information for the client was lost and well spread in kind of website,

and the network in our office was supervised. So he think that it may be stolen by someone with the uses of the usb devices.

So, does winXP have anything to supervise the access of these type of usb devices??or is there any software can help me to do so??

plz give me some reply as soon as possible~~
