Hello Corsair forum.
I just recently got 2xll140 and 1xll120 to match the rest of my corsair setup. My keyboard (k95) and AiO (h115i plat) both shows up in the iCue software but the fans doesnt show up. Both the commandor pro and node is connected to sata power and the cables are connected to their proper destinations. The fans spins and light up, which indicates that they both recive power.
Here is a picture where the USB is connected on my asus z370-g: here
Heres a picture of someones elses setup but it looks like mine, except for the motherboard pictures and so on. here
