USB-Blaster - error while programming NIOS II

[antibalda]

Hi community,

I am newbie in FPGA. 

I have Cyclone IV kit from rzrd.net with USB-Blaster cable. It worked fine to yesterday. After windows update I have problem with downloading program to FPGA and to NIOS II (yes, I use NIOS II processor).

Error message in Eclipse is :

There are no JTAG cables available on your system which match the --cable option you provided (USB-Blaster on localhost [USB-1]).

Of course, The Quartus Programmer doesn't see the USB-Blaster. 

Hovewer, after restart the Windows, I can download the program to FPGA only once - this is successfull. After this successfully download, i dont use USB-Blaster for other times. I dont undestand it. 

What I try :

Reinstall Quartus Prime IDE - no effect. (I use version 18.1).

Reinstall USB-Blaster drivers - no effect.

Try "Windows Recovery" to previous date - no effect. 

Try other USB-Blaster - it same like first USB-Blaster (same error). 

On other PC (without Update from Microsoft), all work fine. 

Please, help me, how to fix it on my main PC. 

Thank you very much.

Hi,

The error is due to USB blaster are not detected. Have you try the following setting on windows?
