[SOLVED]ModemManager 0.7 breaks support for Ericsson F3607gw WWAN card

Hello,

apparently the ModemManager v 0.7.990 currently in the repos no longer supports my WWAN card, a Dell 5540 Mobile Broadband (which is just a rebranded Ericsson F3607gw).

ModemManager 0.6, which is the version used in Fedora 18, works just fine with the card and connections can be made.

My device, as listed by lsusb:

Bus 008 Device 004: ID 413c:8184 Dell Computer Corp. F3607gw v2 Mobile Broadband Module

The output of the log with MM 0.7:

Apr 25 00:43:18 brb-laptop ModemManager[1823]: <info>  ModemManager (version 0.7.990) starting...

However, I cannot downgrade to MM 0.6 as Gnome 3.8 and NetworkManager require >=0.7.


Has anyone encountered this problem before and has a fix/solution? Or should I file a bug in the Arch tracker? I got Bluetooth PANs to work with a patched bluez from this board, as the upstream version is behind the one used by fedora (4.101-1 vs. 4.101-4). WWAN is the only thing that doesn't work with my new Arch setup.

Thanks in advance, any help would be much appreciated.

I did, you linked to it already smile

I slightly modified modemmanager-git in the AUR and added some dependencies, the git version now works for me.

Works for me too. Thank you. big_smile

PS. It is new, that I must activate the ModemManager in systemd?

systemctl enable ModemManager
