jskeepalive - keeps a joystick alive
jskeepalive <device-name>
jskeepalive continuously reads from the given joystick device. (This
doesn’t prevent other programs from accessing the same joystick
device.) This is necessary for certains joysticks which disappear if
they are not accessed during a given interval (see
https://bugs.launchpad.net/ubuntu/+source/joystick/+bug/448446).
