Raspberrymatic as Unraid Docker Container

[cablesky]

Hello!
I want to run Raspberrymatic in an Unraid Docker container because I don't want to set up a VM in Unraid.

Everything works fine except for the passthrough of the HMIP-RFUSB stick.
I built one myself with an FTDI and a Homematic module, which has been running flawlessly in a Proxmox VM for 2 years (also via passthrough).

Unfortunately, I can't get it to work under Unraid. No hardware is detected at all.

I have already tried the steps described on

https://forums.unraid.net/topic/102062-run-raspberrymatic-as-docker/?do=findComment&comment=1044626

with

modprobe cp210x
echo "1b1f c020" >/sys/bus/usb-serial/drivers/cp210x/new_id

Here, I do get a /dev/ttyUSB0 device, which I then passthrough mount into the Unraid Raspberrymatic container, but no hardware is detected.

Where does Raspberrymatic actually look for hardware? Also in /dev/ttyUSB0?
Which modprobe do I need to choose/activate?
@jens Maus: Can you provide any insights on this?

Thank you in advance!
