Trying to understand what this error means : RPi ,Signalink , direwolf , ax.25 , kissattach / pat

Good day all. Exact same error when the Signalink USB is plugged into the board itself and when plugged into a powered hub.
Clean install of stock Stretch - only adding direwolf, the ax.25 stuff , and pat. 
Any idea what the following direwolf error dump means ?
