I'm pretty well clueless as far as the input stack is concerned, so I hope I am aiming this report at the right place :)
When I insert the Microsoft Nano Transceiver 1.0 (which comes with the MS Mobile Mouse 6000, for example) three input devices are created. Naturally, one of those corresponds to the mouse I am using, the other two are for other devices it could have been connected to. xinput lists these as two pointers and one keyboard. One of those pointers is a joystick (which udev sticks at /dev/js0).
Even though I have no joystick associated with that transceiver (or indeed any joystick), games see that device and use it. The phantom joystick's position seems to be tilted upwards and to the left; in tumiki-fighter (where I noticed the problem), I am unable to control the game because I am stuck flying to the upper left corner of the screen.
Here's some fun stuff…

Later I tried running
% jscal -c /dev/input/js0
It crashed, but indeed zeroed the imaginary joystick, so tumiki-fighter cooperated.
If more data is needed, I am happy to provide it!
Original bug report follows:
Binary package hint: tumiki-fighters
Weird issue with this game. The ship appears to be stuck flying up and to the left. Thus, it is impossible to move down and the ship is always being pushed leftwards. This renders it unplayable ;)
At first, it appears as thought the Down control simply does not work, regardless of which one I use.
It may be specific to my system. I ran the Windows version of the game in Wine, and it works there. However, I did notice that controls became stuck in a similar fashion when another process rudely grabbed the keyboard and mouse, so the game is evidently quirky in how it handles input.

I can't reproduce this issue. It sounds like your problem is due to another program rather than an issue in tumiki-fighters, do you agree with this analysis? If so, please close this bug.
