Quartus prime and USB Blaster II

[Surya12]

Hello there,

Please have a look at the attached image. I have successfully installed the USB blaster II driver from the device manager and my device manager can acknowledge the device. But the Quartus prime tool does not show any attached hardware (USB blaster). Can anyone please help with this?

That might be due to issue with USB Blaster II. Kindly follow the workaround in KDB below (it is also applicable for USB Blaster):
