Operating System: XP Pro SP1. My boss connected his Palm Pilot to the front usb port of his computer. The computer froze.
He cold booted it and it would not recognize his usb mouse. There was no light to the optical led. I used a PS2 mouse and checked the device manager. It shows "unknown device" whenever any usb device is installed in any usb port, front or back. It does not show a yellow error. I uninstalled and reinstalled the usb drivers and and the problem remains the same. I did a sfc /scannow to no effect. I did notice that there is no " generic usb hub" listed. Any ideas on what I can try next.
