USB Disconnects

[Teberon]

Hello,

Yesterday I installed Proxmox as I am looking for a host for my homelab. My first vm was home assistant and I was looking for a way to add an USB device to the vm and it was not that complicated, but since this morning I have an issue with the USB device

Anyone here to shed some light into what could be the reason and how to troubleshoot that further? In case you need some more logs/information please let me know.

Currently I use Kernel Version Linux 5.4.73-1-pve #1 SMP PVE 5.4.73-1

I was digging a little bit more into it and found this
https://www.davecorder.org/tag/linux/
Seems to be perfect fit. But unfortunately it does not help...
in /etc/udev/rules.d/99-deconz-1.rules I added
SUBSYSTEM=="tty", ATTRS{idVendor}=="1cf1", ATTRS{idProduct}=="0030", ATTRS{serial}=="DE2423760", SYMLINK+="zigbee"

That gives me the symlink in /dev but the unit is still reconnected all the time
