Unable to passthrough usb dongle to hm vm

Hello together,

Long story short:
I am unable to passthrough my sonoff zigbee 3.0 usb dongle plus to my home assistant vm (installed with pimox) on a raspberry pi 4.

This is my output on the node

root@pimox:~# lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
    |__ Port 2: Dev 2, If 0, Class=Mass Storage, Driver=uas, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/1p, 480M

root@pimox:~# ls /dev/serial/by-id/
usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_b44ff8ce6829ec11859f757840c9ce8d-if00-port0

It is the usb dongle on Bus 1, Port 1.3

I am passing the usb dongle to my ha vm via the proxmox GUI. But home assistant does not recognize it. In zigbee2mqtt says “there is no /dev/ttyUSB0”.

Can anyone help me maybe?
