identity forcing of multiple usb-blasters

When multiple blasters are installed, how does the driver make the determination of which one is -0 and which is -1, etc? Is it based on the order of initial driver installation? My experience...

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.

Look at the registry entries for each USB-Blaster on the two computer systems. Does the number at the end of the "Driver" field correspond to the [USB-x] order on each computer?

Cheers,
