[beagleboard] Problems connecting to a beaglebone

There is only one single USB port on that board. It is configured to show up as a USB device (the storage drive) and a RNDIS (Ethernet connection) both of which you say you have successfully accessed. Gateone access is an issue it seems a lot of people have had. You might try searching the list and see what others have done.

There are no com ports from this board over the USB.
