The code you need is actually in modemmanager. I have 0.5-1 and it works
for me ( I am running Debian sid though). It was fixed as part of this
bug: https://bugzilla.gnome.org/show_bug.cgi?id=660998
The network interface from GobiNet would be inactive because it needs to
be configured via the USB device GobiNet creates using GobiAPI.
Another thing, NetworkManager dont see qcserial and I am running the
last version from oneiric repository which is 0.9.1.90.
Last thing, when I load GobiNet NetworkManager see it as a unplugged
wired cable, and I cannot do anything with.
