HP Omen 25l ; Corsair iCUE 4000x

Hi, 

In a nutshell I have a HP Omen 25l GT12-0045na Desktop.

I wanted to upgrade the CPU cooler and the case - for which I chose the NZXT Kraken x73 and Corsair iCUE 4000x.

The CPU cooler works and is properly set up, apart from the USB connector that supposed to go into the internal motherboard connector, but I used the external USB port for that.

The Corsair iCUE 4000x case was compatible too, however, the Corsair Lighting Node Core - that comes with the case - is not being detected by the motherboard's 9 Pin USB connector.

And I know the connector works because I was able to hook up the NZXT cooler to it with no issues.

I have all the correct software installed and drivers up-to-date.

The motherboard is just not detecting the Corsair fan RGB controller for some reason.

If you open the Windows "Device Manager" (right-mouse click on the Windows "start" button), is the device listed as "unknown device" or "device-drivers are missing" ?

Experiment: power-off the computer, disconnect the 9-pin connector from the motherboard, and power-on the computer. Connect any memory-stick to any USB port. Do you hear any noise from your computer's speakers as Windows detects that USB-interface memory-stick? Further, do you hear the similar noise when you connect the 9-pin connector to the socket on the motherboard? Or, no noise?

The device manager only shows all the USB devices apart from the Corsair Lighting Node Core, same with USBDeview.

I’ve tried disconnecting/reconnecting it multiple times but there’s nothing to indicate that the motherboard /Windows is recognizing the hardware. 

There is a possibility that the Corsair LNC is broken, but my suspicion is that the HP Dorado motherboard is just not compatible for no apparent reason.
