Thanks, but that did not work. It continues to give me the message: "The data is invalid". I have even tried using the drivers provided on cds that came with the various usb mice even though they should all be plug and play. I cannot understand why I can use USB keyboards, flash drives, speakers, etc. but I cannot use a usb mouse.
I have also tried disconnected the PS2 mouse just in case it was causing a conflict, but I still get the same error. I would like to know where it thinks the data is bad so I could replace it.
