Ahhh damn it.

One of my units appears to have died after two days of use ( from receiving ).

USB becomes unresponsive, all the expected lights come on. Primary bank has all lights on (tx/rx/idle/valid), second bank just has the idle light on. Taking the end of the board with the molex connector as the top, the top left hand side of the board gets very hot (80-100 deg) used my IR temp gun to check board temps.

Any ideas? From visual inspection I can't see anything out of the ordinary, if there was a short surely a fuse would have gone.. but it all seems fine.
