[PVE-User] USB Expansion Card for PCIE Hub passthrough?

[Lindsay Mathieson]

Thanks everyone for the useful info.

nb. I did try passing through my Motherboard USB as its not used by the 
proxmox install, but that was a disaster. Shares IOMMU groups with the 
disk controller...

Yeah, thats the trouble with the cheap and cheerfuls, getting solid info 
on the chipsets is a minefield.
