Public bug reported:
I have a USB modem Huawei E3251 (DC-HSPA+ USB modem).
It is a 3G device, although not quite a usual one: In the NetworkManager applet
it shows itself as an ethernet or wired connection.
How to reproduce the bug:
1.) Have a PC (with ubuntu 14.04 LTS) which is first turned off. Plug
the modem into one of its USB ports.
2.) Turn on the PC and boot the ubuntu. (It logs me automatically.)
Unfortunatelly, after the boot the NetworkManager is completely ignorant
of the modem and networking does not work.
If I want to start networking anyway, I have to physically unplug the
modem and plug it again. This is pretty annoying.
BTW, if the networking is finally working and I just restart the
machine, the networking works after the reboot. It even connects me
automatically.
