Unknown Devices helps you find what those unknown devices in Device Manager really are.
By checking Device Manager for unknown devices and extracting information from it, this program attempts to figure out what the device is. You might not have to open your case or look up random numbers off of PCI cards to figure out what they are.
Program supports Win95, 98, 98se, Me, 2k, XP and 2003 but not NT. It also attempts to support future OSes.
