Hi Martin.

I have attached the output. Case a is with a combined wireless usb
dongle for a microsoft keyboard. Case b is for a wired usb keyboard
(logitech) and wired mouse (hp). Case c is with just the mouse. The js0
is not created for the last case.

I am of course interested in getting the bug fixed, but even more in
learning how to debug and fix it. So any details about what you think is
wrong would be much appreciated :)

Title:
  udev: /dev/input/js0 is created but no joystick attached

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  With ubuntu vivid i see a /dev/input/js0. I do not have a joystick or
  gamepad attached. This invalid input device cause a game in steam
  "Crypt of the necrodancer" to crash during start. The game works fine
  when I delete it.

  This appears to be a ubuntu specific bug as it does not show up on
  fedora 22.

  It goes away if I unplug the mouse/keyboard usb dongle I use. If I
  attach a wired keyboard only it does not show up. I tried adding a
  wired mouse too, but that causes js0 to appear too. The output of
  udevadm changes depending on what mouse I have attached. The following
  output is from using the dongle for my wireless mouse/keyboard (both
  microsoft products)

  $sudo udevadm info /dev/input/js0
