Public bug reported:
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:
