Hi, been reading through this thread and I can't find an exact answer to my situation:
I have a PCI (LEGACY) USB 2.0 card i want to passthrough to VM.
I've tried different methods to separate the PCI card it is own IOMMU group. No luck. ACS Override, downstream option, vfio PCI. Combination of all of them
Rebooted in between all those changes and the VIA USB Controller in group 11 will not move. CPU/Mobo is compatible. Version 6.5.3
Will this ever work or is this a limitation because it's PCI (Legacy)?
Does the PCI card need to be separated from the group in order to attempt OP's workaround?
Thoughts/ideas?
