Bug Description

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.
