OH2 & Ubuntu core, no serial port

I’m trying to connect on an OH2 snap installation on ubuntu core the serial port for the aeotec zwave controller gen5. It worked before with an apt-get installation with /dev/ttyACM0. Now I always get following error:

OFFLINE - COMMUNICATION_ERROR Serial Error: Port /dev/ttyACM0 does not exist

I’ve read something about configuring with the “snap connect” command ther serial port. I have no idea how it works. Can someone help me?

USB port access is currently an open issue in Ubuntu Core. You might want to follow up on that thread.
