When a WM5 smartphone is plugged into its USB cradle, the establishment
of the RNDIS session to communicate with the phone fails because of a
driver bug negotiating an improper frame size with the device. The dccm
daemon would therefore not detect the phone and no dialog is possible.
Testing: User has tested against patched kernel, plugging and
unplugging various other USB devices (printers/cameras/scanners...) with
no noticeable negative effects. See above comment.
