See mjg59's reply and my note on USB suspend elsewhere in the thread. (OS X turns off lot of things using non standard firmware implementation and uses out of band notifications that Windows and Linux aren't made aware of. Apple's Boot Camp drivers also turn off USB suspend on Windows. Those things matter a lot for power management.)
