Thanks all! I have identified the board.

As a bonus, the machine is still under warranty so I am working with Canaan on that now. Once I got in touch with them, they have responded within 24 hours to each email from me.



To add to everyone's random information bank....

It appears that the ECHU ( 0  0  0) in the log represents the ports on the control board (looking from the back of the machine) (Left, Right, Middle).
