USB-Blaster can't be found

Hi Olav,

Are you using Window 10? Have you try to disable driver signature enforcement? If not, can you follow the steps below to have your USB Blaster configured properly:

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 - If your boot drive is BitLocker encrypted, you'll need to enter the recovery key (press return, enter the key in the text box then hit return again - it took me three goes to realize I had to hit return before I could enter they key !)

6 - You'll be given a menu of options, number 7 disables driver signature enforcement

7 - When the PC restarts, use Device manager to update the drivers - this time you'll get a warning about the signature, but they install fine.

8 - When you've finished, restart normally to re-enable signature enforcement

Thank You.
