Comment 17 for bug 621743

i have excatly the same issue!
added the ignore rule for modemmanager, placed the right firmware, appearently, it used to work some times!
i was already online with the new modem, under win7 it works flawless.

and in maverick i got trouble to load the device. and i changed nothing since last usage a few days ago.

the gobi firmware loader just hangs up.
