My class at CU-Boulder uses the Terasic DE10-Lite board and Quartus Lite. Over the past two years students sometimes run into the issue of the USB_Blaster driver not installing properly, but updating the driver from Windows device manager always worked. This semester, a significant number of students cannot get the driver to install using this older approach.
The problem is due to the USB-Blaster driver being unsigned, and a large number of the Windows installations have settings that won't allow installation of an unsigned driver.
https://www.technipages.com/enable-disable-device-driver-signing Option 2 solves the problem, so students have been able to progress.
The big question is what are you doing to resolve this? Why the driver is unsigned is the big question, as this would solve it quickly. Next question is why can't I find any resolution on the Intel website? My class cannot be the only class running into this. Since many classes are remote due to the pandemic, these types of issues are brutal to resolve.
Thanks for the feedback. First of all, i would like to check which quartus version are you using?
You may check with our Intel KDB for more workaround for any problem:
This problem is occuring on Quartus-Lite 20.1 and, but the class last semester used the same Quartus version and did not see this. I believe something changed in Windows recently.
The underlying issue is that the USB-Blaster driver is unsigned, and Windows doesn't like it. Isn't the customer friendly thing to do would be to get the USB-Blaster driver updated so that Windows doesn't refuse to install it?
Or, at the least, document and publish a series of steps that would assist your customers?
Please don't just send me a canned email telling me to look in the Knowledge Base, that is zero help.
Thanks for your feedback. It seems like we have the solution provided in the forum thread previously. But you are right. Will discuss this with internal team and issue a KDB if appropriate.
