From: Krister Walfridsson
Subject: [SDL] src/joystick/bsd/SDL_sysjoystick.c patch
The *BSD USB HID joystick code has two serious bugs:
1. If a joystick reports unhandled hid_input usage (for example HUG_RZ or
HUG_DIAL), then the last handled value will be overwritten with an
arbitrary value. (Fixed in the patch below by adding a default case.)
2. The current code does only handle logical coordinates in the range 0-255,
while a big part of available joysticks report -128 - 127. (This is solved
in the patch below by first center the range around 0, and then stretch
it to the correct range.)
