I agree with you about making libusb act more like IOKit, but I also feel 
that libusb should act the same on all the platforms it has been ported 
to.... So, it would take some work (and proabably kernel-level code?) to 
do so. So, I dont think it should be done but I am willing to write the 
necessary code if the other developers of libusb disagree w/ me?
