identity forcing of multiple usb-blasters

This is the experiment I originally performed on a colleague's computer (and referred to in the original post) to test the theory:

a) plug both devices in

b) uninstall each blaster's device driver using device manager

c) reconnect board A, then board B, auto-reinstalling blaster device drivers in the process

d) correlate the blaster ID's to the physical board

then repeat the above but swapping the order of re-installation in step c

I got identical results both times: board A was always USB-0 and board B was always USB-1

HOWEVER, when I repeated this experiment on my PC, the USB-0 blaster is always the last one installed. The boards used on my PC were different than the boards used on my colleague's, so there may be something to that. All should have unique serial numbers, though.

Maybe more experiments are in order.
