Hi,


Do you still facing this issue?


Kindly try below:

  1. Ensure that USB Blaster Adapter connected to the board in correct manner(one to one mapping)
  2. Complete reinstall of Quartus Prime
  3. Running as admin

Another try:

  1. Disconnect other USB device
  2. uninstall and reinstall the usb blaster driver
  3. If you have another USB Blaster, please try using another one and see if it works.


Regards,

Aiman
