Hello Vicky,

Thank you for your answer. Unfortunately I have already done those steps. That is what I did to get the driver for the USB Blaster, so the software recognizes the USB blaster is connected. The problem is that device chain is not being recognized. The quartus software says that there are no devices in the chain.

If I connect the DUT to the older XP system with the parallel port byte blaster, it has no problems seeing all of the devices in the chain.
