Hi jzucker,

Sorry for the confusion. What support meant by this is that you can use either TimeFactor's USB port or TimeFactor's MIDI IN and OUT ports to backup sounds as well as to update the OS. If you think that the USB port on your particular unit is faulty then as a matter of troubleshooting you could try the same operation via the stompbox's MIDI ports and see if that works. This requires that you use an external MIDI interface to connect TimeFactor to your computer.
