	I did -- this is what gave me a little hope in the first place :) 
However, as you say, connecting to the thing seems to be the fundamental 
problem at the minute :(

	Well, I did originally try with just the numbers ("0 0"), and the 
program suggested that the only available options were "/dev/usb0" and 
"/dev/ugen0" -- so I stuck with them.  I *think* (from vague reading of 
the libusb code) that the BSD-specifics allow/use device-paths rather 
than bus/device positions; though I may be wrong there :)

	Certainly -- see below; again, with libusb debugging switched on for 
extra noise ;)

	I'll see what I can do to fetch/build this tonight/tomorrow and post 
back as soon as I can.  It feels so close, yet so far away :-/
