Would this proffer a possible solution?

Other forum members having different issues have had them resolved by updating to the latest 5.5 kernel.

I installed Fedora32 and it seemed to work and is visible in the menus:


In case of ZorinOS the Input/Output device selection seem fail somehow… I hope it get fixed ASAP.

Just done a search on kernel used by Fedora 32 and it is up to 5.8.6 already - it might be worth seeing if updating to 5.5 as I suggested earlier might resolve this issue - remember the kernel has drivers for hardware embedded in the kernel - Zorin provides the ‘skin’ if you like - in much the same way Fedora provides the ‘skin’ for the kernel it uses. I know I am over-simplifying this but just trying to put it in to simple terms. :wink:

So, I hope to know if later kernel is available. It could be kernel version related.
