After loading or reloading the Operating System on a computer, several entries show in Windows Device Manager as "Unknown Device". Typically this requires opening the case and trying to determine the manufacturer by reading screen prints on the card or chipset, etc. An easier method is to use the software tool "Unknown Devices" by Halfdone.
