I have also done next to no high level Mac OS X (or other OS) programming. My
regular programming consists of working on linkers, dynamic instrumentation
tools and compiler components.

But it's really not that hard. For the Mac OS X HID stuff, look at the HID
Calibrator stuff I mentioned in comment 39, the HID headers
(/System/Library/Frameworks/IOKit.framework/Headers/hid and .../hidsystem) and
the existing code in joystick_osx.c. I also found the USB HID documentation
useful for background information:
http://www.usb.org/developers/devclass_docs/Hut1_11.pdf

The Linux DirectInput code is in joystick_linuxinpuc.c, the winmm code in
joystick_linux.c. The code in both files seemed fairly similar at first sight.
In fact, at first I had no idea why both were present and while searching for
their purpose I found a thread on wine-devel where someone proposed merging
them (but that was deemed to be not that easy because of the differences in
models between winmm and dinput).

In any case, by putting linux_joystick.c and linux_joystickinput.c side by
side, and joystick_osx.c next to that, I don't think it should be that hard to
create a Mac OS X version for winmm. I don't have any games that require that
though, and even if I had I currently don't really have time for it either.

Good!
