(SOLVED)Not able to passthrough on-board USB controller - iommu group not viable

[sit_rp]

Not sure why this is not working. I have ACS override enabled.

Any thoughts?

 

 

 

EDIT: (SOLVED) If you take a closer look at group 8 you will notice that 04:00.0 is one of the device that was placed into that group. It's a PCI ethernet adapter. I removed it (physically from my system) and now group 8 doesn't have any issues with pass through. Cheers.
