Public bug reported:

usb_modeswitch kernel module tells me to report this bug :)

The modem works fine, it's just not stable.
Unplugging and reinserting creates a kernel oops that seems to prevent halting 
the system.

First time I plugged it in, I got an U-DEV popup error message. A little
after that, there was a question about PIN code and the modem worked.

Unplugging and reinstering the device, it won't work. I have to reboot.

I added four lines in usb_modeswitch.conf:
DefaultVendor=12d1
DefaultProduct=14fe
TargetVendor=12d1
TargetProduct=1506

At the last reboot, this made the U-DEV popup disappear and the modem
asks for the PIN and works.

The work_device.txt attachment shows the kernel log for this event.

I will upload the log for when I unplug and reinsert the device as a
separate file.
