Comment 0 for bug 1424181

What happened:
I have to unplug and plug my Huawei E3372 USB modem in order to connect to the Internet. Otherwise the Internet connection is not established. The problem is present in kerner versions 3.13.0-45 and 3.19.0-031900. However, xubuntu 12.04 works fine.

Expected to happen:
The computer should establish the Internet connection automatically.

Steps to reproduce the bug:
Plug the USB modem into the computer and switch the computer on.

I use Ubuntu 14.04.2 LTS.
