After entering the registration form (XP can enter "regedit" in "Run", 2k input "Regedit32"), in "edit", "Find" enter "Usbstor", only select "Item", do not select "value" and "data" can speed up the query. Then "OK". Kill all the items found with "Usbstor" (click "F3" for each item you delete). If you can't delete it, right-click on "Permissions", go to permission settings, and select "Allow" Full control. If you are not sure, in the registry, click "My Computer" and then press "F3" , and then the query is deleted once.
