I bet, right now someone somewhere must be searching for "hidusb.sys and mouhid.sys" over the internet.

Now the question is: What are hidusb.sys and mouhid.sys for? Have you purchased any USB mouse, USB stick or USB keyboard? There you are, you will probably be asked to "insert" any of the two files to continue while installing a new USB mouse or keyboard.

These files are Windows System files. They are not dangerous, virus, or Spyware and they are not even very large.

Don’t try searching for them on your PC, may be you would not have them if XP is asking for them.

I have spent few days finding them myself.

You can download hidusb.sys and mouhid.sys!
