Which USB ports should be used on a MacBook to connect the audio device?
Due to internal routing of the USB ports in many cases only a certain USB port is working properly for using an USB audio device on MacBook Pro's.
You need to check in the Apple System Profiler (in Utilities) under Hardware->USB if your USB audio device shares a USB High-Speed Bus with another USB device or not. If necessary, try another USB port on your computer. Finally the USB audio device should not share its USB High-Speed bus with any other device.
In some cases it already helps to take the USB audio device away from the USB High-Speed Bus that is shared with the internal iSight camera.
The audio interface should be connected to a different USB port as the iSight Camera
A general recommendation for all types of MacBooks (MacBook Pros) about the best USB port cannot be given.
