I just did a clean install of XP Home in a friends PC which has an Asus P4S800 mobo and a via firewire card. I'm assuming that one of the 2 'unknown device' exclamations that I'm finding in device manager is referring to this. He didn't get any discs with the card as it came installed and I'm at a loss to find them anywhere. I can't get windows to find it either so I'm not sure what to do. Any ideas what to do or how to determine for certain what these 'Unknown Device' listings refer to?
