Like I said earlier, I added the user to the dialout group (using that usermod command below) and that fixed my issue.
My system does not show /dev/ttyUSB0 as locked (I can't say for sure if that was the case before I added dialout to the user's groups. "stat /dev/ttyUSB0" does contain Gid: ( 20/ dialout) Todd Zuercher P.

Thanks Gene, I'm not sure that, bug is completely relevant to my issue. As my Mb2hal config never used serial/by-id. It has always used /dev/ttyUSB0 to address the RS485 device. Maybe serial by id might be a better way to address the specific serial port used, but I am not even sure if it is even be supported by Mb2hal or exactly how to set it up that way (none of the example Mb2hal configurations use it.) And even if it were possible, I'm not sure if I still would have had the permission problems and I would have also had to fix the udev bug first. Changing the permission is all I needed to do to get this working as it was before. Todd Zuercher P.
