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...

Download FTDI's FT_PROG and plug in the USB-Blaster's one at a time.

Use the Devices->Scan and Parse menu function to read the contents of the FTDI EEPROMs.

That'll help confirm the serial numbers are unique.

Yeah we use FT_PROG to program the FT245R devices in our boards (custom, with an embedded usb-blaster). I just said "should" be unique because I don't know that the engineer that tested those boards initially followed the procedure.
