Proxmox + Z2mqtt + zbt-2

Hi All. For the life of me I cannot get the new ZBT-2 working with z2mqtt. USB port is mapped and configured correctly. Firmware is up to date on everything. Z2mqtt keeps complaining about usb not found. I can swap config back to Zbt-1 usb port and it works again immediately. Home assistant integration correctly shows ZBT-1 and 2. Installed ZHA and ZBT-2 works fine.

Any assistance is appreciated

HA 2026.1.
Z2M 2.7.2-1
ZBT-2 7.4.4.6
