Not the answer to you question, but I have some problems with USB on AU1200 board too. I use AirStar2 USB card (this is DVB-T card) and it is recognized by AU1200 and can communicate with it. I can tune to transporder, but the data (transport stream) is not send from the USB card. The card conforms to USB 1.1. I tried it on a PC running Linux and it works fine. AU1200 kernel: 2.6.11, PC kernel: 2.6.13.2. Any thoughts?
