I am having a serious problem with my brand new A7V133A also. I have the latest revision of the board, 1002 w/audio. I am only using two slots, 3com 3C905B-TX, and an ATI AGP video card. I have an Athlon 850, PC-100 128MB(x2), 300 watt PS, Maxtor 30GB 7200 ATA/100 HDD and an Asus 50x CD-Rom. I have installed all of the latest drivers from ASUS, Promise and VIA. However, much to my disappointment, my USB scanner refuses to work more than once per cold boot. I have already tried 2 CanoScan N650U scanners. And last night I tried the brand new HP ScanJet 2200C. I have zero apps loaded on the machine, except for the scanner software. The scanner is recognized on the initial boot into 98SE. When I click on the 'Scanner/Camera' icon from the Ctrl Panel and choose properties the scanner is available. However, when I test communication with the scanner the communication fails...every single time. I spoke with ASUS tech support today. I spoke with this real genius who tried to pawn the problem off on the HP and Canon scanner drivers. I told him this was unacceptable because this is the THIRD USB scanner I have tried. I asked him if he really expected me to swallow this nonsense he was feeding me. It was insane. I might as well have asked my black lab to help me out. I told him there are known problems with Asus/Via re: the A7Vxxx and he acted like I was the first person to every tell him this. This guy was simply pointing fingers to HP and Via. It's amazing that ASUS is not addressing the deep rooted problem with there board/chipset configurations. I was also really surprised with any USB testing being completely omitted from any of the reviews I read. I bought the board because of the great reviews it received. So far it has been nothing but a nightmare. If I could do it over I would steer clear of this board until 2-3 months have passed. Maybe next time someone will perform a thorough test, including the USB devices.
