Hi Dave,
The connection process is very similar to what I have been doing, and I see the green LED light up and right at the beginning, the other green LED (I think it's related to LiPo charging) usually also gives a short blink (I guess it's until it figures out there is no LiPo connected), but I see nothing in the terminal.
When I get home tonight I'll try to see if the board isn't fully inserted, that would explain the trouble.
I'll let you know how it goes!
