So I bought a Corsair Commander Core XT this weekend and I installed it today. It partly fixed it because my rear fan now lights up in white, but OpenRGB hasn’t been able to detect it yet. I haven’t been able to control the fan RGB and change the color as a result. I did not connect the Commander Cores up to each other yet. The Commander Core XT has an optional 3 pin RGB C header and one USB 2.0 headers that I did not connect up. Should I try connecting either of those from the XT to the other Commander Core?

Okay, so is it possible to use and plug two Corsair Commander Cores into each other and then have them both be detected by OpenRGB?

I think that it’s a Corsair fan hub that I had connected to the Corsair Commander Core controller. Would OpenRGB be able to detect the fan if the hub is connected to the controller that way, even if it is not listed as a device? I’m beginning to suspect that the fan hub connection came loose somewhere, but I haven’t had an opportunity to check it out yet.

Both the Corsair Commander Core controller and the ASUS ROG motherboard are being detected in OpenRGB, but there is a 7th fan controller that is separate that is not being detected. That’s the one that is out.

What should I do if the attached controller appears to be missing and rescannig for devices doesn’t bring it back?

Titanfall 2 is on sale for $4.50, and it has an excellent singleplayer campaign. You can tell em papa Scorch sent ya.
