The same problem occurs with Ubuntu 16.04 LTS.

Cold-boot, particularly, this seems to fail.

Basically the problem is that usb_modeswitch_dispatcher is called with
incorrect arguments.


# systemctl --all | grep usb_modeswitch
● usb_modeswitch@1-9_1-9:1.0.service                                            
                        loaded    failed   failed    USB_ModeSwitch_1-9_1-9:1.0
  system-usb_modeswitch.slice                                                   
                        loaded    active   active    system-usb_modeswitch.slice

# systemctl status -l usb_modeswitch@1-9_1-9:1.0.service
