Description: mode switching tool for controlling "flip flop" USB devices
 Several new USB devices have their proprietary Windows drivers onboard,
 especially WAN dongles. When plugged in for the first time, they act
 like a flash storage and start installing the driver from there. If
 the driver is already installed, the storage device vanishes and
 a new device, such as an USB modem, shows up. This is called the
 "ZeroCD" feature.
 .
 On Debian, this is not needed, since the driver is included as a
 Linux kernel module, such as "usbserial". However, the device still
 shows up as "usb-storage" by default. usb-modeswitch solves that
 issue by sending the command which actually performs the switching
 of the device from "usb-storage" to "usbserial".
 .
 This package contains the binaries and the brother scripts.

Title:
  usb_modeswitch@.service fails

Status in usb-modeswitch package in Ubuntu:
  Fix Released

Bug description:
  I lack the technical knowledge to know if this is a bug in udev,
  systemd or another component.

  After the switch to systemd, my 4G Huawei USB modem  no longer
  functions as a modem unless I run usb_modeswitch to flip its state
  from USB mass storage. The command I issue and its output is below,
  which also show the Vendor and Product ID.

  Strangely, it does not do this every time. Yesterday when I updated
  using apt-get dist-upgrade upon reboot the modem worked as expected.
  But from a cold boot this morning it did not.

  $ sudo usb_modeswitch -v 0x12d1 -p 0x1f01 -J
  [sudo] password for damon: 
  Look for default devices ...
     product ID matched
   Found devices in default mode (1)
  Access device 003 on bus 003
  Current configuration number is 1
  Use interface number 0
  Use endpoints 0x01 (out) and 0x81 (in)
