So I got 2 kits of 3 riing plus fans. Conected 5 fans in the first controller, the micro usb on the same controller and the usb on the motherboard. Connceted the last fan on the second controller and linked the two controllers, also switched the first DIP switch up, on the second controller (to be recognized as controller 2). Started the software but it doesn't recognize the second controller, so I can't set the lighting effects of the fan on the second controller to be the same as the fans on the first controller. Any ideas on what's wrong here?
