USB Blaster

Hi Masif,
 

Could you confirm whether the USB-Blaster is detected by the operating system and share the output of jtagconfig?

Please also provide:

• Quartus Prime Pro version
• Operating system and version
• USB-Blaster model
• Any error message from Quartus Programmer

If the cable is visible to the OS but not Quartus, please check or reinstall the USB-Blaster driver, restart the Quartus JTAG server (jtagd), and reopen Programmer. You can also try another USB port and ensure no other application is using the JTAG connection.

The jtagconfig output will help us narrow down the issue.
