Hi I couldn't find an Asrock group so I thought I'd ask in here. I have 2 new K7S41GX boards from different sources both with the same fault (?) Operating system is XP Pro Service Pack 2. Only 3 out of the 6 USB ports work - 1 of the 2 front ones and 2 of the 4 rear ones. The dud rear ports are the upper left and lower right ones (looking at the back of the case). I've tried disconnecting the cable to the front USB ports in case there was a wiring problem on the header cable, but no change. Also tried removing all the USB devices in Device Manager and letting Windows find them again. According to the driver CD, the board doesn't need any special USB2 drivers installing if you have Win XP Service Pack 1 or later. I tried 2 different devices (memory stick and digital camera) with no luck. Any ideas? Am I missing something obvious? DM
