I was thinking more of a Novatel-specific override in the Novatel plugin... there is one more bug too. The novatel plugin should be treating USB interface 0 as the modem/dial interface and the second port as the auxiliary port, but if the device has already been switched to two-port mode with AT$DMAT=1 then if ModemManager is restarted, it might find the second port first and use that as primary. And I don't think my 5510 likes that very much either.
