It's a QFP so the errors are OK.

Turned out to be a bad solder joint on pin 1 of the USB connector 
(power). Connector on this card is not very mechanically stable with the 
mounting posts going into huge worthless holes. :-(

Error messages were just a red herring, after not having seen them for 
weeks while working on the SAM9G20.
