How to stop MM from configuring a specific modem?

[Msquared <nmlist msquared id au>]

Hi!

How do I configure ModemManager to ignore a specific USB 3G modem?

I have a 3G USB modem that I'm using with gnokii to reprogram phonebooks
on SIM cards.

Since I do not use the device as a modem, ModemManager interferes with
gnokii when the modem is first plugged in.


So far I've only been able to completely disable MM or uninstall it, to
stop it from interfering with the modem.

I tried adding the device to NetworkManager's unmanaged-devices list, but
of course that just stops NM from using the modem; it doesn't stop MM from
configuring the modem.

Is there a way to stop MM from messing with a specific modem?
