Copy comments from KittyHawk project -

After installing modemmanager_1.0.0-2ubuntu2_amd64.deb from comment #5, WWAN works.
Speed test result: 37.05Mbps download, 15.97Mbps upload.

Also tried S3 and hybrid sleep, WWAN works after S3, but didn't work
after resuming from disk in hybrid sleep.

  novatel: improve probing for Dell branded modems

Bug description:
  Dell rebrands modems from different vendors, including Novatel, Sierra
  and Ericsson. Until now we defaulted to the Novatel plugin when a Dell
  device was found, but then we're breaking newer MBIM Sierra Dell-
  branded modems, as we don't have MBIM support in the Novatel plugin.

  So, we should try to improve the probing in the Novatel, Sierra and
  MBM plugins, so that they probe also Dell devices, and we'll then try
  to match via AT-probing which plugin should be handling the Dell
  device.

  Could we backport this patch  into trusty? Thanks!
