My rear fan RGB stopped working when it was connected to a Corsair RGB hub. I originally had one RGB hub and one Corsair Commander Core. I bought a Corsair Commander Core XT over the weekend to replace the RGB hub and I installed it. It partly fixed it because my rear fan now lights up in white, but OpenRGB hasn't been able to detect the rear fan RGB 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?

My rear fan in my desktop PC used to be detected in OpenRGB until about a week ago after I installed some firmware updates for my Asus ROG Strix Z690-A motherboard. All of my 4 fans and my cooler are from Corsair, and three of the fans are plugged into one Corsair Commander Core. The Core is still being detected by OpenRGB, but the rear fan is not anymore. If I recall correctly it is managed by a Corsair RGB header. Additionally, My GSkill RGB RAM works but it is now being detected as a generic ENE DRAM. If I try to rescan devices nothing changes. What should I do?
