Great.  My new kernel driver (Streams module) went from 1500 lines of code
down to 500 lines.  In fact, maybe I don't need this at all.  I could use
user level code to send the appropriate info directly to the hid driver...

Yes, but for usb hid devices, suspend/resume should be handled by the 
HID driver, no?
