When I connect usb devices to my case usb ports connected via the additional connectors on my P4P800 mobo (ie not plugged into the backplate) I get a message saying not USB 2. I have tried updating the drivers from the ASUS mobo cd and from the net but am always told I have the latest drivers. I am running XP Pro with SP2 so as far as I know the drivers should be correct for USB 2. Any ideas?
