I have searched a bunch and couldn't exactly find an answer, but I did find a reference to it in a way. The double usb hookup on one side of the cable- it's used only to increase power- throughput- when running real tracks from the usb drive? I've only used one thus far, NOT the red one. I thought that was perhaps for another usb recording device. But plug in both for extra speed? If using only one, is there a preference, black or red?

Thanks. I just can't seem to find this answer!
