Sure thing, here is the output for IOMMU: /sys/kernel/iommu_groups/0/devices/0000:00:00.0 /sys/kernel/iommu_groups/1/devices/0000:00:02.0 /sys/kernel/iommu_groups/2/devices/0000:00:03.0 /sys/kernel/iommu_groups/3/devices/0000:00:14.0 /sys/kernel/iommu_groups/4/devices/0000:00:16.0 /sys/kernel/iommu_groups/5/devices/0000:00:1a.0 /sys/kernel/iommu_groups/6/devices/0000:00:1b.0 /sys/kernel/iommu_groups/7/devices/0000:00:1c.0 /sys/kernel/iommu_groups/7/devices/0000:00:1c.2 /sys/kernel/iommu_groups/7/devices/0000:00:1c.3 /sys/kernel/iommu_groups/7/devices/0000:02:00.0 /sys/kernel/iommu_groups/7/devices/0000:03:00.0 /sys/kernel/iommu_groups/8/devices/0000:00:1d.0 /sys/kernel/iommu_groups/9/devices/0000:00:1f.0 /sys/kernel/iommu_groups/9/devices/0000:00:1f.2 /sys/kernel/iommu_groups/9/devices/0000:00:1f.3 I have a fairly new Asus Z97 motherboard with i5. So it has VT-d, and the motherboard bios has a ton of options for xHCI and EHCI. Default it is set to pass all the USB ports to the xHCI controller. Would there be a way possibly to set it up so the 2.0 ports are on EHCI and 3.0 on xHCI, then that should split them up on different buses as well as different PCI addresses, as the 2 unused EHCI controller each have their own PCI address as well. Appreciate the help in finding it the solution for this!

I never did get any USB ports to show up on Bus 3 or 4 which both have their own PCI address. While Bus 1 and 2 share the same PCI address.

I was trying to get this to work, however I have my all my USB ports split between 2 different Bus, but they are both on the same PCI controller. Am I still able to pass-through the bus that does not have my unRaid USB attached to it, even though they are on the same PCI controller?
