When I sent in some SDL fixes last December, I found out they'd already been fixed in the CVS version. This time, I checked the repository before bugging you. =) I'm using SDL-1.2.5 on a FreeBSD 4.6.2-RELEASE system, and in the course of getting my multi-analog-axis USB controller (with a hat switch!) working with d2x-sdl -- the SDL port of the Descent 2 engine -- I came across a few problems: 1) The second analog stick is reported as a slider in one direction, and "Rz" in the other. SDL was ignoring the Rz axis, so I added Rx/Ry/Rz to the set of things SDL considers to be axes. 2) After the above change, the set of JOYAXE_* axes for my gamepad was {0,1,3,7}; however, d2x-sdl expects the axes to be contiguously numbered from 0, which seems like a pretty reasonable expectation, rather than having to scan the entire space of axes that SDL may or may not have. So, I added a table lookup which maps the JOYAXE_* axis numbers to 0,1,... in the order they're detected by SDL_SYS_JoystickOpen(), when reporting them to the application. I also added a function "usage_to_joyaxe()" which maps the USB HUG_* usage values to JOYAXE_values, since the repeated case statements testing for HUG_* were getting out of hand. 3) The BSD joystick driver had no hat support, so I added it. It looks like our USB library can only support one hat switch per device, which makes life easy. The patch against SDL-1.2.5 which implements these changes is at: http://www.caida.org/~jabrown/patches/sdl-1.2.5-bsdhat.diff After applying, SDL's "testjoystick" reports all activity from my gamepad correctly, and d2x works too (though it needed some other fixes). Moving on... There is also a problem with slightly different USBHID library interfaces on different versions of FreeBSD. I wasn't going to mention this since the FreeBSD port for SDL-1.2.5 (and not SDL itself) was doing the FreeBSD version-specific patching, so I e-mailed the port maintainer with this change. However, I see that you've incorporated the FreeBSD version-checking stuff into the CVS version of SDL, so now it's relevant for you too. The problem is, the FreeBSD #if tests don't work right for FreeBSD 4.6.2-RELEASE. There may be other versions with this problem, but I've only tested 4.6.2-R. The following patch against your latest CVS version fixes this: --- SDL_sysjoystick.c-1.16 Tue Apr 15 09:02:08 2003 +++ SDL_sysjoystick.c Sun Jun 1 15:10:28 2003 @@ -420,6 +420,8 @@ # else len = hid_report_size(rd, repinfo[repind].kind, r->rid); # endif +# elif (__FreeBSD_version == 460002) + len = hid_report_size(rd, r->rid, repinfo[repind].kind); # else len = hid_report_size(rd, repinfo[repind].kind, &r->rid); #endif I hope this is all useful to you. I've been getting myself dizzy playing Descent 2 with it, all morning! -Jeff Brown P.S. My USB controller is a Thrustmaster Firestorm Dual Analog 2. That's probably irrelevant, but I threw it in for completeness.

    OpenGL in window mode  works well  and  stable, in fullscreen
mode too, but fullscreen mode has not been heavily tested.
    If you have QNX RtP 6.1.0 w/ or w/o Patch A you must download
new Photon3D runtime from http://developers.qnx.com. The versions
of OS before 6.1.0 are not supported.

Problems:
1. While  creating  OpenGL  context  software  renderer  mode  is
   artificially selected (QSSL made acceleration only for  Voodoo
   boards in fullscreen mode, sorry but I don't have  this board,
   if you want acceleration - you may remove some line  in source
   code).
2. Photon has some errors in detecting  how  much bits  per pixel
   videomode has.
3. No  shared  libraries  yet.  We  need  manually  set  flag  to
   'configure' --disable-shared.
4. Due to Photon API limitation, flag SDL_HWSURFACE supported on-
   ly in case of desktop bpp is equal requested bpp in window mo-
   de.

Some building issues:

    Run configure script without x11 support, e.g.:

    a) for OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared

    b) without OpenGL support:
    ./configure --prefix=/usr/local \
                --disable-video-x11 \
                --disable-shared    \
                --disable-video-opengl

    In test directory  also run  ./configure  script  without x11
support, e.g.:

    ./configure  --with-sdl-prefix=/usr/local      \
                 --with-sdl-exec-prefix=/usr/local \
                 --prefix=/usr/local --without-x
