It’s a known issue that will most likely be fixed in the next release.
In the command line, execute following command every time after you boot your raspberry pi:
sudo chmod 777 /dev/ttyACM0
This will allow the webserver to access the usb key 😉
The core service also does not start automatically, this is also a known issue.
But looks like you managed to get it started.
