So apparently, it's opened by mplayer. Indeed, by default mplayer always
opens the first joystick device, because some people like to  control a
movie with a joystick.

I don't think much can be done from the kernel point of view. Maybe
there are even people who enjoy controlling their movies by moving their
laptop! Here, my ~/.mplayer/config looks like:
[default]
input=js-dev=/dev/input/js8

You could also put a udev rule to change the name of this joystick to
something like js1.

All I could think of in the kernel side to improve this situation would
be to give more information about joystick devices, and define a subtype
"accelerometer", which mplayer could avoid selecting by default. I don't
know enough the input interface to know if this already exists...

See you,
Eric
