Title:
  ModemManager does not seem to recognize Sierra Wireless EM7305
  (Fujitsu Lifebook S904)

Status in ModemManager (with NetworkManager support):
  Unknown
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):
