Altera USB Blaster problems, findings and sources.

Hello Aqid,

I have checked out the links you provided. They were helpful up to a point in that the problem is a bit more defined now: expired certificates. It is likely that if I install Quartus 21 with the patch that the driver will work. I've noted that version 21 no longer has MultiSim, at least not by that name, so I stuck to 20.1.1.

I do have more useful information though. And that is that I had installed Quartus 13.1 once more, to be exact, version 13.1.0.162.

I then proceeded to install the USB Blaster, which installed successfully. And so I can now confirm that the USB Blaster driver with the aforementioned version works.

However, since the installation problems for the newer Quartus versions pertain to expired certificates, I went to see what the certificate information was for the driver supplied with Quartus 13. The information said the certificate was supplied by VeriSign to Delaware Altera. And not just that, also the dates: Valid from 6/28/2011 to 8/24/2012. So this looks like an expired certification also. And yet it works.

You will find 2 attachments: The certificate properties screenshot for this driver and a zipfile containing this driver.

Since I can get around with this driver and still use Quartus 20.1.1.720 with MultiSim, this is what I'll keep using for now.

Hope this helps with future driver releases.
