OpenHAB And Zwave

[revoman]

I just received my Z-Wave module (US version).  What port does the zwave module bind to?  and I assume by the size that it fits on top of the Pi2 headers.  I've tried to map the controller to /dev/ttyS0, /dev/ttyS1, /dev/ttyS2, /dev/ttyS3 and /dev/ttyS4 with no success, all I get is "Port /dev/ttyS0 does not exist".  
I have also tried adding

-Dgnu.io.rxtx.SerialPorts=/dev/ttyS2:/dev/ttyS0:/dev/ttyS1:/dev/ttyS3:/dev/ttyS4

to the runtime/karaf/bin/setenv file as a JAVA_OPTS.  

Here are the groups my user has been granted:
openhab@openhab:~$ groups
openhab tty dialout sudo plugdev


Ok,  Here are some snippets from my logs by starting OpenHAB with /opt/openhab/start_debug.sh 

(when trying to access /dev/ttyS2)

Code:
