Title:
  Swisscom USB modem doesn't work

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  I recently purchased two Huawei USB modems E372 from Swisscom in
  Switzerland, but none of them works. When I try to activate it in
  Network Manager it immediately fails silently. I used to own the
  previous USB model proposed by Swisscom (can't remember the model and
  I don't have it anymore, but it was a Huawei too), and that one worked
  very well.

  Here are the last few lines from /var/log/syslog:
