Problem with USB passthrough

[pisiiki]

Hello!

I have set up a ProxMox machine with a Win11 guest, however I'm finding it difficult to make my USBs work correctly. I have a B550 motherboard with a Ryzen 3700x and a Geforce 1060. I have added the 1060 and the USB PCIe to the Win11 VM config.

Without any other config, just after installing ProxMox and setting up the Win11 VM, everything works fine. However the USB's only work after the 2nd boot of the VM. So I have to start the VM, stop it and start it again. After that the USB's work correctly.

Any help would be appreciated.
Thanks!

Isaac.

Does it work the third time or only even times? Maybe it's a reset issue. Try early binding it to vfio-pci so that the Proxmox host does not touch it before starting the VM. Add the device ID to the options vfio-pci ids= line if you already have it. Don't blacklist the USB driver, because you might lose all other USB ports as well.
