I am attempting to reinstall Indigo on El Capitan after foolishly upgrading to High Sierra.
The 2414U controller is visible in System Information.
Now I am getting connection failed errors.
I have replaced the USB cable and it made no difference.
Someone suggested that there might be permission errors. Is this a possibility and if so where?
I am able to use Z-Wave devices They function correctly so I think Indigo 7 is OK.
Another suggestion was that there might be noise on the line. I've tried using an extension to several other outlets but I'm not 100% sure if it is on a different circuit.
