Just as a comment, that might help someone else finding this thread, as I did in my despair.
I was having trouble with a similar error log on a raspberry pi 3. It had worked, and after I had fiddled with completely unrelated things (shell_commands, and scripts, none of which involved anything z wave), it stopped. For me it wasn’t the usb path (that was usb_path: /dev/ttyACM0
, and hadn’t changed from when it worked), and to be honest, I don’t know what it was. At some point I might have done an apt-get update
.
For me, the solution was to do an apt-get dist-upgrade
.
The output of my home-assistant.log
was:

I just hate googling to find that thread that almost, but not quite, solves your problem. So I hope this will help someone searching…
