Instruction Guide I recently brought this device. I am not able to play my ipod connected to this device using the USB interface. Thanks in advance for your help. How does it identify, browse and show on display the various mp3 file folders on SD card ? Is this the correct one that I need in order to use my Apple USB SuperDrive with my 13" MacBook Pro Laptop?
