[SOLVED] usb controller passthru

[almiller]

I have a usb3 pcie card in a Dell R710 that I'd like to passthru to a Windows guest.

I can't passthru usb devices connected to the pcie card because the Dell isn't recognizing any devices plugged into the card's ports.
(assuming that is because the Dell doesnt support usb3?)

The iommugroup is uniq for the device I want to passthru

root@proxmox ~ # pvesh get /nodes/proxmox/hardware/pci

But I also see this:

root@proxmox ~ # dmesg -T | less
....
[Mon Nov 25 08:45:57 2024] DMAR-IR: This system BIOS has enabled interrupt remapping
                           on a chipset that contains an erratum making that
                           feature unstable.  To maintain system stability
                           interrupt remapping is being disabled.  Please
                           contact your BIOS vendor for an update

How do I assign the above USB 3.0 Host Controller to my guest? Would that be

qm set 112 --hostpci0 host=0000:04:00.0

Nevermind, I think I got it working. I also forgot to set the machine type to q35.
I was also able to get the Win10 guest updated to win11.

My pcie USB3 host controller is passed to my guest and I see the 2 usb cameras attached to it now.
