Bug description:
  Recently I have noticed that Zoom In/Out slider on my Microsoft
  Ergonomic Keyboard 4000 stopped working. I tried investigating what's
  wrong and noticed that my keyboard reports as two different input
  devices according to evtest

  sudo evtest output:
  (...)
  /dev/input/event2:      Microsoft Natural® Ergonomic Keyboard 4000
  /dev/input/event3:      Microsoft Natural® Ergonomic Keyboard 4000
  (...)

  /dev/input/event2 responds to normal keys
  /dev/input/event3 responds to multimedia keys and zoom in/out keys

  The most puzzling thing is that multimedia keys actually work and be
  bound. For example I have bound KEY_F17 to Next track in Amarok.
  Play/pause, Vol. Up/Down and Mute worked out of box.
