Public bug reported:
My Huawei E220 dongle has started to disconnect every now and then.
It can run fine for several hours, but suddenly it can disconnect and I
cannot connect again no matter what I do (click reconnect, physically
disconnect the USB-device and plug it back in).
The only solution is a reboot after which everything is just fine again.
Here's a log that's hopefully around the time of a proper connection of
the device followed by disconnection and several attempts to get it
connected.
