There is a sample code, though buggy, that lists the devices, and  
makes it easy to see what variables a HID device produces:
   http://developer.apple.com/samplecode/HID_Manager_Basics/ 
listing3.html

In order to get it compiling in Xcode, I had to do the following:
  * Create a Carbon project.
  * Add the unpacked sources (just drop the whole directory into the  
project).
  * Add /System/Library/Frameworks/IOKit.framework (add from Project - 
 > Add to Project)
  * Change a couple of comparisons of NULL to 0 (with mach_port_t  
derived types, like io_iterator_t).
  * To test a joystick, in the file HID_Manager_Test.c, the line  
following "Finding GamePads", change kHIDUsage_GD_GamePad into  
kHIDUsage_GD_Joystick.

This way, when running it, with the Xcode Console visible, I could  
(using <control>-T) get a printout of the joystick parameters. Try  
changing this last line into kHIDUsage_GD_MultiAxisController, and see  
if you get anything.
