I have looked around, and from what I can see, one needs to make some  
new code for it. In Chuck's source file util_hid.cpp, for joysticks,  
the Mac OS X HID API variable kHIDUsage_GD_Joystick is used, which is  
mentioned in
   http://developer.apple.com/technotes/tn2007/tn2187.html
which describes the general HID USB interface. Then netsearching for  
"spacenavigator hid usb type Mac OS X" led to
   http://www.3dconnexion.com/forum/viewtopic.php?t=34
which says:
   The LED is an ordinary HID output. I am able to control it from Mac  
OS X using the OS-provided HID APIs.
   Look for an element of type 129, then set its value to 1.

So it seems that it is a regular USB device, but not one in those  
specific classes: some other programming with that API will do,  
though. Just my guess.
