Just checked out today's git of NM and MM: It registers and connects
fine now!

It still asks for the password and MM sometimes tries to use the ttyACM2
device which fails. Disabling and enabling the card again usually works
and MM either uses ttyACM0 or ttyACM1 which are both fine. This issue
was also present in the stable release!

Thanks,
