Cant find ZBT-2 - proxmox

Hi!

Running HA on Proxmox.
Using:
Proxmox Virtual Environment 8.4.0
HA 2026.1.1

I can find my ZBT-2 on proxmox using lsusb:
Bus 001 Device 012: ID 303a:831a Nabu Casa ZBT-2

Using USB passthru I can set thh ZBT-2 to my HA.

But my HA cant find it. It wont show up as Discovered when adding integrations in HA. I cant find it under Hardware in HA.
I´ve updated the ZBT-2 Zigbee and Thread firmware using a different computer.

What am I doing Wrong?

For anyone with similar problems.

Got it working by first shutting down the VM in proxmox before adding the passthru
