@landpatterson Great! /dev/ttyUSBx is Linux machine id for serial port. In windows it would be like COMx. So you can enter as follows,
Driver: For windows you can select either jssc or jSerialComm. I would recommend you to leave it as Auto. It will select best driver for your OS. We no need to specify a driver until there is a situation.
I guess in windows port name should be without space COM5.
Retry frequency: When there is a loss in serial port connection between MyController and your gateway, MyController will try to reconnect after this x seconds. here I have mentioned 120 seconds.
After successful connection, you can see debug logs on Status >> Resources logs
