The extra power for the hub was minimal, the point was the the BBB USB was unable to power the dongle.
The actual hub I used was of a size intended to go into a laptop bag and had a little round 2mm power socket in the side.
I just happened to have a USB power cable from an external laptop hard disk that fitted that socket.
