Thank you WAWA. I placed the NANO with the USB connector jack facing the same side as the power Jack of the shield and before connecting it I compared the markings of the shield and the NANO.Thanks
Perhaps I'm wrong, but looking at the shield it has the expanded pins on the upper side labeled from 0-13, with rx/tx on 0/1. Typical numbering goes CCW around the board, so that tells me the USB connector should be opposite of the shield plug-in
