The beaglebone wouldn't boot with nothing attached and just plugged into USB, but will boot with barrel jack power. Last night I cut off the end of a USB cord and stripped the black and red wires. I plugged the black into P9_1 and the red into P9_5 and it boots! So I'm not sure what I broke but at least I can still use it. Thanks, Jordan
