I have an A7N8X deluxe and it seems despite my efforts I cant get USB2.0 on it. every time I plug my Zen Xtra in (2.0 device) it complains its a high speed device in a low speed port. I have service pack 1 installed, every driver on asus's site installed (except for the extra ethernet), and the updated forceware (whatever its called). please help, its taken 7 hours to copy 3k mp3s!
