got it up and running… yes!
the cure? added the serial binding. Did not have to do that for Windows version and for that matter don’t recall a ‘serial’ binding. Anyhow, also restarted system and openHAB before seeing signs of success. PaperUI opened with two zigbee motion sensors in the inbox & both controllers z-wave and zigbee online
Thank you Chris Jackson for these terrific bindings. Anybody want to buy a hue or smartthings hub?
For the record Linear HUSBZ-1 works great in Windows and Linux
edit to add link to thread where serial binding hint made in post 7
