As Taylor said, your SDL_LINUX_JOYSTICK is incorrect.

You didn't say what driver you use (joydev is an interface, not a
driver), but I presume it uses hid as it's a USB device? In which
case, you would be better using the evdev interface.

However, SDL 1.2.5 will use the joystick before the event interface
and depending on your distribution might not have event support
compiled. Either try with evdev only (unload joydev), or try SDL
1.2.6 with event support compiled in.

Thats up to Dan, but I think your patch is unneeded.

People know how to use the joystick interface as its been around
forever! Set it up correctly for SDL and all the other games will
also work without having to add joystick code to each game.

The joystick interface is being replaced by event interface. (Though
it could stll do with a calibration method :-)
