Comment 16 for bug 755342

The problem is obvious in the log from #14:

Warning: SCSI attribute "vendor" not readable.
Warning: SCSI attribute "model" not readable.
Warning: SCSI attribute "rev" not readable.

The filter "sMo=U209" which should prevent usb_modeswitch from doing anything in this case does not work - because the SCSI identification fails.

The problem is in the dispatcher part of the Ubuntu fork of usb_modeswitch.

ikletti, can you check out these SCSI attributes in the /sys tree when your phone is plugged in?

You'll find it under
/sys/bus/usb/drivers/usb-storage/<device>/host*/targetX:X:X/X:X:X:X
