ConbeeII keeps disappearing in KVM-virtual machine

General

Dear all,

Since 1st of December I have the problem that phoscon in my home assistant cannot connect to conbee firmware any more.

My setup:
Core i3-8100 debian 11.5 (uo to date) VM-host
libvirt virtualization
HAOS in virtual machine with 2 cores and 4 GB of RAM.
conbeeII connected by extension cable to USB2 Port

Stable service till 1st of December 22.

Now conbeeII is recognized on USB but phoscon shows firmware not connected.

conbeeII connected to Windows 10 PC connects and shows firmware.

conbeeII in another VM with fresh install of debian 10 or 11 and deconz installed shows in deconz 1-2s “connected” before button gets greyed out.

Does anyone have any suggestions? I am totally in the dark (literally).

Firmware was updated to latest version on Windows 10. No change.

Best regards,

Marco

Just reactivated an old Pi and installed phoscon on it. Works since. Wanted to reduce the number of devices but… Maybe I will switch to zha or ZigBee2MQTT on home assistant in the future.

Hi Marco.
I have had the same problem and never managed to fix it. I could not find a solution either. What I did instead I run deconz in a docker on the host. Home assistant finds it automagically anyway and that gives you the flexibility to have it connected to multiple things/instances if you wish for it :slight_smile:
Not a fix but better than an old pie perhaps. :thinking:
