Hi,


My understanding on the issue is that, you are having issue to install USB Blaster driver on windows. Please let me know if my understanding is not correct.


You may refer to the guide below for USB Blaster installation on Windows:

    That worked!!!

    Really appreciate your response. I have a class of 20+ students using this first thing in the morning, so you've really saved the day.

    I didn't see anything flagged related to certificate issues and would not have considered it. It was odd that a 20H2 build on my home machine was OK, I was starting to suspect a recent Windows update.

    Thanks again.

    Andrew

    I've noticed that the driver signature expires 18th June 2021. Is there going to be another update?

    Also, is 21.1 going to be made available for the Lite edition?

    This procedure does not work. I am using Win 10 Pro, USB Blaster and "intelFPGA_lite 20.1.1 quartus drivers usb-blaster" after applying the patch. Device Manager shows "Unknown USB Device (Device Descriptor Request Failed)

    I suggest you install Quartus 20.1.1 lite , attach a USB Blaster and see if it appears in the Quartus programming window.

    Right now I can not program an Intel FPGA. Perhaps I should try using a Xilinx part.
