I have a Vista Ultimate pc that is getting a USB Unknown device error. The nerror occurs with no USB devices plugged in. I go into the device manager and uninstall the unknown device driver but it comes back on reboot. I disabled the onboard USB ports in setup then rebooted but when i turn the ports back on the unknown device error comes back.

Look for M'Board Drivers that are not installed. Quite often the Default Windows Drivers do not suffice for some M'Boards.
