Hi Guys,
Today I tried to install deconz, additional to ZHA.
It was a bad idea, because my ZHA is not working anymore… even when I uninstall deconz.
The problem is, that the path to the usb stick cannot be found.
Do you have any idea how to solve this problem?
All my lights are not available anymore and my wife wants to kill me. 
When I installed deconz, I updated the Phoscon Gateway.
I think that is the reason why it is not working anymore.
Error from Logs:

I found out that in Hardware I cannot see my ttyACM0.
I assume that there might be a problem with my conbee 2 stick and not with HA.
Here you see a screenshot from my supervisor logs.
Am I understanding it correct, that HA is removing the device? Why??
dmesg:
lsusb:
ls -lha /dev/tty* (no ttyACM0 found)
+
ls /dev/serial/by-id (Dont know why, but suddenly conbee dresden stick appears)
solution found:
The firmware of the conbee 2 was corrupted.
I removed it from Raspy and added it to my Windows USB Slot.
Here the USB slot also lost the connection every 5 seconds.
I downloaded the latest version of Deconz and installed it through windows.
