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...

Some GPUs have USB and often you can passthrough an internal USB controller that
is provided by the CPU. Those usually work with passthrough.
None on mine (GTX 1070) unfortunately :)
Please search the internet/forums for a USB controller that is known to work
with passthrough.
Many cheap devices use a USB-chip that does not reset properly. Sometimes
manufacturers change
the chip without warning for a cheaper one. Level1techs forum might help:

Thanks!
Currently looking at a Orico 7 Port USB 3.0 PCIe Dual Chip Card.
Sorry, but I have no experience with that one. Check what chip it uses
internally.
Yeah, thats the trouble with the cheap and cheerfuls, getting solid info
on the chipsets is a minefield.
Best of luck on your hunt for the right USB controller.
Thanks! I'll post here if I find anything.
