Bug 1036293

Description of problem:

3G Dongles no longer work with Fedora 20 (Beta)  ModemManager is not loaded.


Version-Release number of selected component (if applicable):

ModemManager-1.1.0-2.git20130913.fc20.x86_64


How reproducible:

Always


Steps to Reproduce:
1. Plug in 3G dongle
2. wait

Actual results:

Nothing happens.

In the background, USB detects the dongle.  usb_modeswitch triggers.  Systemd attempts to load ModemManager.  Systemd cannot find ModemManager


Expected results:

Somehow magically the 3G network becomes available in the network list.


Additional info:

ModemManager is i686 ONLY in Fedora 20 ???  Rest is x86_64.
