ModemManager 0.7 brakes support for Qualcomm Gobi 2000
Hi!
Since the upgrade to modemmanger 0.7 I've lost my WWAN support for the Qualcomm wwan-card with gobi-loader.
Read in another thread [SOLVED]ModemManager 0.7 breaks support for Ericsson F3607gw WWAN card that they made some modifications to modemmanager-git and it seems that people has got it running since. But no luck with my Qualcomm.
I've installed both modemmanger-git and libqmi-git, but has been unable to get the Gobi plugin of ModemManager to identify the modem.
Been over the udev-gobi rules several times and tried with every possible solution that comes to mind.
Any help appreciated.
If I where to file a bug-report, should I file it with upstream ModemManager@Launchpad.net or with bugs.archlinux.org ?
Below is output from the system:
[root@x201 ~]# systemctl status ModemManager.service

Re: ModemManager 0.7 brakes support for Qualcomm Gobi 2000
Thanks for the reminder! 
modemmanager 1.0 is out and it works, so no need for any *-git package anymore.
$ yaourt -Qs | egrep 'modem|gobi|libqm'

Firmware for gobi 2000 wwan chipset
local/gobi-loader 0.7-4

extra/modemmanager 1.0.0-1
Mobile broadband modem management servicebut my PID is different:
$ lsusb
Bus 001 Device 004: ID 05c6:920**5** Qualcomm, Inc. Maybe uninstalling all the mentioned packages, wipe all remaining files and reinstalling helps.
