Steps to reproduce the issue

2. Install HA supervised https://github.com/home-assistant/supervised-installer Intel atom NUC Debian 11
3. Buy HMIP-RFUSB https://www.amazon.de/gp/product/B07B4DP1KY/
4. Solder HMIP-RFUSB
5. Inset HMIP-RFUSB onto any USB port
6. Install RaspberryMatic, latest snapshot for HA Supervised https://github.com/jens-maus/RaspberryMatic/wiki/Installation-HomeAssistant#using-homeassistant-supervised
7. When RaspberryMatic starts, HA Supervisor throws error messages according to first supervisor log shown in: https://homematic-forum.de/forum/viewtopic.php?p=706012#p706047 (sorry, explanatory text in german, pls. use translate).

According to Jens Maus and others in the RasperryMatic Forum, this error does not occur on HAOS installations, e.g.: #3421 is making th dynamically created devnodes work. But in this supervised install it does not work.
