Passed-through USB port forgotten after restart

[rogierl]

Hey, I'm running PVE7 and I have a problem with assigning a passed-through USB port to one of my guest virtual machines. Each reboot from the PVE host itself results in "forgetting" the port sharing. Please see attached screenshot. So when I reboot the host (PVE itself), the chosen port (2-2) is always forgotten. Why is that?

So when I reboot the host (PVE itself), the chosen port (2-2) is always forgotten.

How do you mean forgotten? Did you set 2-2 and it returned to 1-2, or did you set 1-2 and the device now has 2-2?

Could you post your VM config (both working and broken, if there is a difference) via 'qm config <vmid>'?

Exactly what you're saying. After a restart of Proxmox, indeed the host value is 1-2.
When I select the correct USB, then it becomes 2.2

WRONG



CORRECT

Any tips?

Sorry for the delay. If your still experiencing the issue, can you post your VM config ('qm config <vmid>')? Best check it multiple times, i.e. once when it's in "broken" state after reboot, once after you fix it, after running the VM, shutting it down, etc...

Thanks for your reply. I now choose the "Use USB vendor/Device ID"-feature and everything works as expected now.
