Try #6 here:

If that doesn't solve it, try the 5.13 kernel.

Thanks -- that should do the trick: apparently the driver isn't signed properly. This will probably be fixed in the near future.

In this case: the user is dual-booting Windows 10 with MINT 20.2 and declined to disable secure boot.

However: I had an EDI Max USB dongle in my parts box and this worked for him.

thanks again :)
