@scorcho99 Do you have the model numbers for the Startech cards you own that is confirmed working?

Disabling IOMMU is system wide. It's all or nothing. If you don't need passthrough, disable IOMMU, some (if not all) USB 3.0 cards atleast, tend to work better, in my experience.. There should be no hypervisor drawbacks, your VMs should function like normal. A fast way to disable IOMMU for me, was to add "iommu=soft" to the startup parameters...

Hi. The key word here is "SuperSpeed". I assume your card have something called UASP support? I have been struggling with a USB 3.0 card with UASP (or "SuperSpeed") for a while, and I too am unable to get it working properly with UnRaid. Too me, it seems like the passthrough is broken for any cards or devices requiring UASP.. However, the cards work with UnRaid, but ONLY if you disable IOMMU (which defeats the purpose if you want passthrough..), then they work fine, devices show up and the card is working like it would on bare metal.
