I had the same problem, on my case NetworkManager was selecting a random
device from the 4 devices recognized from my Vodafone 3G PCMCIA Card.
I was directed to the following wiki page:
Fortunately on my case the problem is already fixed on the daily trunk,
anyway I would like to understand how it works to isolate the fix and
backport to the stable version.
I was investigation my problem based on HAL information (lshal,
10-modem.fdi) from looking into similar bug reports, after looking at the
modemmanager source I have found I was looking at the wrong place since udev
is now used replacing HAL.
>From mm-manager.c I have found that mm scans/handles devices with subsystem
"tty" and "net" .
You can get a list of the currently detected udev devices with:
udevadm info --export-db
Now. I need to find where is the modem date retrieved from I guess there is
an equivalent to hal-info with the modem information.
Hope it helps.
