This is my first time seeing this kind of behavior. So, I am quite stumped.

Curious, does the device part name show up correctly in the working machine? instead of 0x2E320DD

Do you mind to share the project so I could check whether the same issue occur from my side?


Best Regards,

Hi Richard,

I have fixed the problem by reinstalling the USB Blaster driver of rev.20.4 (rev.19.1 was failed with " file corrupted" info). Partially reason, I guess, might be that I did not have administrator level authority for the machine. The system just blocks it. But, I still don't know why it was working at the beginning when I installed the Quartus two years ago and later it became failure. Perhaps it was intervened by some security software installation since then. What I did today was just wiped out the driver totally and reinstall it with the admin authority. It works now. Weird, isn't it?

Anyway, very appreciate your helps!
