Does the ATC700 contain a USB connector?
- Because it supports RGB Fusion, it should be connectable to any RGB Fusion header (3-pin Addressable RGB) on motherboard (Z390 Designare does not have this).
Or does the Gigabyte C300 Glass contain a RGB lighting controller into which the ATC 700 is plugged?
- If so, is the RGB lighting controller connected via USB to the F_USB header on Designare?
One workaround is to connect the RGB lighting controller to an External USB port on the rear IO panel. We can use a
9 pin USB to USB 2.0 cable to do this. Then if you run IORegistryExplorer and export the IOReg file (File --> Save As...), we can help you disable that external USB port in macOS. This allows Windows to control RGB effects, but hides the device from macOS.
