Z-wave setup seems to be OK, but device add not working

I believe I have the z-wave component set up ok, since the config panel is now showing up. When I try to add my first z-wave device (I only have one to test since rest of the house is currently on Insteon) I don’t get a successful add.

Here is the log. Its clearly full of warnings and errors so I likely have something set up wrong. Any/all help would be much appreciated:

(i get a 520 error when i try to post the log as text so I’m attaching two images)

It looks like Open Z-Wave is not communicating with the controller properly, let alone the device you are trying to add. What controller are you using? Have you given the homeassistant user access to the stick with the command below (which appears in the docs)?

$ sudo usermod -a -G dialout homeassistant

neglected to say thank you for your response. Turned out that simply restarting HASS allowed it to see the Aeotec stick the next time.
