ConBee II - Deconz failure after Pi Bullseye update June 16 2023

the conbee II gateway no longer was reachable in deconz app and phoscon app
see: https://github.com/dresden-elektronik/deconz-rest-plugin/issues/6937

Summary of workaround

need to add a --dev=/dev/ttyACM0 to the deconz startup

cmd line example: '/usr/bin/deCONZ --http-port=8008' --dev=/dev/ttyACM0


deconz.service example: ExecStart=/usr/bin/deCONZ -platform minimal --http-port=8008 --dev=/dev/ttyACM0


while using /dev/ttyACMx is a workaround it could also randomly fail due to how Linux "randomly" assigns these paths so that ttyACM0 sometimes becomes ttyACM1.


once this debian fix needs to make it into pi https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1035094
    you can remove the --dev=/dev/ttyACM0 from the deconz startup
