The Driver file details are correct. It is normal to have mutliple drivers per device.
I have attatched some examples from my system. All the devices is my system are working correctly including the USB Mass Storage.
Did USBSTOR.SYS get restored automatically? It is not a good idea to remove windows drivers, could cause further problems.
Thanks for the reply.
Microsoft Windows 7 HP x64 downloaded the file and replaced it back in system32.
Thanks for the advice.
