Just to chime in, yes and no. You can't pass a port, you can pass a single
device, but it's best to pass a whole USB controller. I also picked up a
USB PCIe card for vfio use, it has two USB 3.0 ports on the PCI bracket and
a header for two front mounted ports, and I have labels from

Thanks.

I initially declined to post, but I think it's even more relevant now. I
just had to replace my GTX 970 for very similar symptoms. While using it
via vfio/passthrough, I'd occasionally see the screen go black or freeze,
but the VM was responsive (sound, network working). I ended up takin
hin 30 days, if necessary.

re if this is related.
I noticed a posting from "S B" in January about a similar problem with
an AMD card, but it didn't seem to have a resolution.
When the card is dead, launching the VM causes this error:
qemu-system-x86_64: vfio: Unable to power on device, stuck in D3
