  If that line is not implemented here, it can not find the device. I 
don't know what else to say, except that, at least on the Mac, it's not 
enumerating and saving the state of the USB bus prior to trying to 
access it at this point. I put a print statement in right under the for 
bus in usb.AllBusses() loop, and it never enters the loop.

  Pardon my python ignorance, but can you please point me to what 
initializes this when the usb module loads, I can't find it.

  As for the "auto" scan bit, I'm not doing those at present on the Mac, 
so if it's counting on them, that would explain it.
