Title:
udev: /dev/input/js0 is created but no joystick attached
Status in linux package in Ubuntu:
Incomplete
Status in systemd package in Ubuntu:
Invalid
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
