Hi Venu,


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. You can also try this https://www.intel.com/content/www/us/en/support/programmable/articles/000073673.html
