are your USB Blasters all of the same rev? i think 2 Blasters of the same rev have the same device ID which does not allow multiple to be on 1 PC.

I think, I also used same revision some times, I can't recall it at the moment, but I can check occasionally. Generally, USB Blaster is enumerated by USB port. If I plug another (also different revision) device, they possibly change their logical port name in the JTAG server (like USB-1, USB-2). So they are apparently not distinguished by revision at this place.
