I just installed a new Mobo (KV8-VM) into my computer (running windows xp). The computer is now working fine, except for the USB ports, which are not responding. Power is still being drawn from them, as my Zen can still charge, but it can no longer be found by my computer. The same is true with a seagate portipal hard drive. When viewing the device manager, I found that the VIA USB Enhanced Host controller has either missing or corrupt drivers. Anyone have any ideas?
