don't unplug the mouse!
i can't remember the exact bios setting, but it has something to do with leagacy usb devices. the choices are primary, secondary, and disabled. if you choose primary, you will have problems with devices plugged into the primary usb ports. if you choose secondary, you will have problems with devices plugged into secondary usb ports.
choose disabled, and all problems go away on rh9.
