Can't connect ZHA to Conbee II

Hi everyone,

I have my ConBee II currently configured via deCONZ but I would like to try ZHA for simplicity. I have installed Home Assistant in a Docker container in Ubuntu, and have tried to add the integration via the GUI, where I get the error that /dev/ttyACM0 can’t be found, and also by modifying the configuration.yaml file like this:

zha:
  usb_path: /dev/ttyACM0
  radio_type: deconz
  database_path: /config/zigbee.db

In this case, the error I can see in my logs looks like this:

Error setting up entry /dev/ttyACM0 for zha
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/serial/serialposix.py", line 244, in open
    self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyACM0'

During handling of the above exception, another exception occurred:

serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyACM0: [Errno 2] No such file or directory: '/dev/ttyACM0'

I have verified that the device is listed under /dev, have changed its permissions and as I said above, it does work with deCONZ. I have also removed modemmanager to avoid interferences with it. The firmware is the latest one.

I’ve run out of ideas and I don’t know what I can do next. Any suggestions? Thanks!
