Thumbs up [Solved] Corsair iCUE not detecting Lighting Node Pro

Recently I decided to add RGB elements to my custom build and ran into an issue with the iCUE control software. I installed the LL140 dual RGB fans (w/ Lighting Node Pro) to accompany my G.Skill TridentZ RGB Ram and Corsair Void Pro Headset, but for some reason iCUE was only detecting my Corsair Voids and not the Node Pro.

... I can't tell you how long I tried to fix this issue myself; what's even worse was the answer was so simple.

Here's the Fix: During installation of the lighting node pro, it will tell you to install the USB cord directly into one of your USB1,2,etc slots on your mobo. If you find that iCUE is not detecting your Node Pro, simply unplug and replug into a different USB slot. That'
Example: For me, I had it plugged into the USB1 slot, and had to move it to the USB2 slot.

Special thanks to Corsair Customer service for giving me the clarity to try this fix. Hope it helps some of you out there with a similar problem.

Happy Building!

I made sure the SATA power connections are working and that the USB ports are both working and no help whatsoever. I even used a different lighting node core to no avail. I really tried everything from reinstalling iCue 3 times and even a fresh windows install. I love corsair but iCue has always let me down. Do I really have to buy a new motherboard and pray corsair iCue will play nicer with this one? I see this problem posted on multiple threads yet there is no fix and this one is marked as a fix but it really isn't.

A) Can you check USBDeView to see if the LNC shows up there? Download USBDeView from If it's not there, it's not connected via USB and iCUE won't see it.

B) If it's not connected via USB, there are several things to try. First, make sure that your chipset drivers are up to date. Windows may autodetect - don't just rely on that. Get the drivers from your motherboard manufacturer. Next, disable Fast Boot in your BIOS and make sure that XHCI Handoff is enabled. Also, disable Windows Fast Startup ( Both of these do stuff with USB detection and can cause issues.
