Please refer to the original bug report if more details are needed.
After resuming from a suspend, the MBIM-managed Sierra Wireless EM7305
doesn't seem to properly allow connections if ModemManager had an open
MBIM session during the suspension. After resuming, a connection attempt
will make the device connected, but not working properly.
[1404835174.470611] (wwp0s20u6c2i12): port now connected
[1404835174.470684] Connected bearer '/org/freedesktop/ModemManager1/Bearer/0'
[1404835174.471132] Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected)
[1404835174.471737] Simple connect state (8/8): All done
(now something happens, and it seems we get a Disconnection via DBus?)
[1404835181.411298] Disconnecting bearer '/org/freedesktop/ModemManager1/Bearer/0'
[1404835181.412289] Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connected -> disconnecting)
[1404835181.412634] Launching disconnection on data port (net/wwp0s20u6c2i12)
Would be good to get a set of ModemManager *and* NetworkManager debug
logs of the same run.

Title:
ModemManager does not seem to recognize Sierra Wireless EM7305
(Fujitsu Lifebook S904)
Status in ModemManager (with NetworkManager support):
Confirmed
Status in “libmbim” package in Ubuntu:
Confirmed
Status in “modemmanager” package in Ubuntu:
Invalid
Bug description:
Ubuntu 14.04, x86_64, ModemManager-1.0.0-2ubuntu1
Card: Sierra Wireless EM7305 (PCI Express M.2 form factor)
Expected: Sierra plugin is used
Happens: Generic plugin is used instead
After cold start the card seems to work almost fine, but does not come
back after suspend or hibernate. At least after hibernate MM may go
into a tight loop consuming 100% CPU.
MM debug log output (full log attached):
