Zwave USB path issues

New to HA so please go easy on me. I have tried the /dev/ttyACM0 per instructions then realized in the system, hardware UI screen that the serial ports are /dev/ttyS0,1,and so on. I changed path to /dev/ttyS0 and now this error occurs. I also now get a button to start the Zwave network in the integration but it never finishes. Any ideas?
