Zigbee2MQTT can't start after migrating from HAOS to HA VM in Proxmox

Installation Home Assistant OS

Hi, I recently migrated from running HAOS on a Raspberry Pi to a VM within Proxmox using the helper script.

After installing in Proxmox I restored from backup, and plugged in my Conbee II usb and setup passthrough to the VM within Proxmox by Device ID

When I attempt to start the Z2M add-on within HA it fails, here is the debug log:

[2025-02-18 19:24:18] error: z2m: Failed to start zigbee-herdsman

I verified within the HA VM that the USB is available, and tried restarting HA, Proxmox and also to remove and re-add the USB device in Proxmox. I haven’t tried installing a Z2M LXC and would prefer to avoid doing so since it seems unnecessary for my needs - having it built-in to HA seems simpler.

My Z2M config:

data_path: /config/zigbee2mqtt
socat:
  enabled: false
  master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
  slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
  options: "-d -d"
  log: false
mqtt: {}
serial:
  port: >-
    /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2483766-if00
  adapter: deconz

If I change the port to /dev/ttyACM0, it matches the adapter but still fails to start with what seems to be the same error:

Did you disable ZHA after reinstalling HA?

I restored from backup which was using Z2M before. Checked now and ZHA is not setup.

Out of curiosity I tried to set it up but it fails with an unknown error - I imagine there’s more info but not sure which log to look in.

Figured out the issue - the new mini PC I’m using only has USB 3 ports, while the old Raspberry Pi only had USB 2.
For whatever reason the Conbee II stick doesn’t work directly over USB 3, but with an old USB 2 extension it works fine.
Go figure…
