USB Blaster help
- 3 years ago
Apparently Intel's drivers for the Byte Blaster are not signed in Windows 10. So Windows doesn't allow them to work.
Here's what I found to get it function:
1 - Go to windows 10 settings and search for "advanced startup options"
2 - Under Advanced startup, hit "Restart now"
3 - After a moment, you'll get a "choose an option" screen - choose "Troubleshoot", then "Advanced options", then "Startup Settings"
4 - You'll get a screen telling you what you will be able to change and a single "Restart" button - press it.
5 - You'll be given a menu of options, number 7 disables driver signature enforcement
6 - When the PC restarts, use Device manager to update the drivers, point to the "drivers" folder in your quartus install directory
7 - When you've finished, restart normally to re-enable signature enforcement
I am using Windows 10 Pro 64b 21H2 and have no Altera USB driver issues.
I have two separate USB pods (a TerAsic Blaster, and a Waveshare USB Blaster from Amazon) and a DE1 board with embedded interface.
They all work fine, and I see 3x USB interfaces installed and available.
I use either Quartus 13.0sp1, 16.0, or 21.1 depending on what I am doing.
Here is what Windows 10 shows about my Altera driver:
