led_device port fails to open

[jgur-psyops]

LEd device port fails to load which crashes the service. Can be fixed temporarily (to allow changing other settings) by commenting out line 70 in led_device.js:

            if (err) {

                console.log('led_device: error opening port ', err.message);        
              //  return reject();      
            }
