I have updated to version 21.1 of Quartus and it does not see my USB dongle. I can run version 19 and the dongle shows up. Any ideas on why the dongle is not being recognized in version 21.1?
Thank you,
Kerry

Hi,
What kind of USB device are you using?
Is it USB blaster I or II?
Thanks & Regards,

Hello,
It is not a USB Blaster. It is a USB dongle for software license. All start with the letter T. It is a locked license that is tied to this USB dongle much like you can with tying it to you hard drive SN.
Thank you,
kerry

Hi Kerry,
As sstrell said, USB dongle is no longer supported by Intel Quartus Prime.
So we can not deal with your issue if you have problem of USB dongle when using Quartus currently.

Hi,
Are there further questions?
We recommended you use a newer cable for programming.
