PCI Passthrough

I'm currently attempting to pass through a PCIe USB controller to a VM in TrueNAS core with the aim of attaching my printers to it allowing me to create a print server that I previously had on an M72 mini pc.

This is the device in question:

This is my Tunables table within TrueNAS:

When attempting to assign it to the VM:

Nothing shows up. Any thoughts or suggestions would be apricated!

Thanks!

It's pretty much right there in that first post (if you take the w to v correction into account).

The missing part at the start is that you run pciconf -lv to see the numbers at the start of that screenshot

You take the last 3 numbers from the bit at the beginning of the line and use those with slashes instead of colons between them in the pptdevs entry.

from that example,

xhci0@pci0:1:0:0:
