OK, if Link isn't detecting the Lighting Node Pro then that's the issue.


Can you post a screen shot of your Link configuration screen? I'm assuming that your H115i Pro is running with no issues, correct?


So let's see what we can do about that. First, make sure that you are connected to a USB header. If you are, then see if you can swap out the cable - you can use any standard mini USB to USB-A cable and plug it into a USB port on the back of your computer.


Also, take a look at USBDeView (http://www.nirsoft.net/utils/usb_devices_view.html) and see if that shows the Lighting Node Pro. You'll be looking for VID 1b1c and PID 0c0b.
