Date: Thu, 18 Jul 2002 23:51:40 +0200 (MEST) 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.)
