Yeah, the PCOFFEN is a command from older, pre-Gobi devices. Not
surprised it doesn't work here, but at least PCINFO does.
It's not an FW image configuration mismatch, otherwise you'd see
IMSWITCH:1.
The device *does* think it's being told to LPM from the card pins. So
you'll need to solve that, how I don't know. You said you already
taped pins on the card, did those include W_DISABLE?
