Look for the USB port associated with ttyUSBRot2 - in this case it is ttyUSB1. Check the serial number of the device on port ttyUSB1:

ATTRS{serial}=="A603G14W"

ATTRS{serial}=="0000:00:14.0"

The serial number of the rotator controller is A603G14W, so this confirms that the rotators are communicating on port ttyUSB1. If the above command gives you a different serial number, edit the command to try each port from ttyUSB0 to ttyUSB5 until you find A603G14W. Now go to the ServoSCommunicator GUI and select the Rotators tab. In the dropdown menu, select the appropriate port - in this case ttyUSB1. Go to each of the Left Rotator GUI and the Right Rotator GUI and click on the pink warning complaining of no comms. If the warning doesn't clear, shutdown and restart all SiTech. ServoSCommunicator should wake up with the ttyUSB1 port selected, and communications to the rotator GUIs should be restored.
