From what I have seen with code using the native OSX HID interface, it somehow 
does not see all the LEDs that are available from the descriptor, which is 
one reason, why I would want to get away from the native implementation.
If the Mac OSX native implementation would be clean, I would not have so much 
of a problem with it, but from my experience, it seems it is not so clean...
Note: I have not really programmed with their HID interface, just have worked 
with programs that use it, and seem to have the mentioned problem.
