Support for ASRock B550 Phantom Gaming ITX/ax and 26ce:01a2 ASRock LED Controller
Installed are Crucial Ballistix BL2K32G36C16U4B RAM kit, Sapphire Pulse 5600xt GPU, and the stock RGB cooler for AMD Ryzen 3700X. I don't have the USB cable hooked up for the cooler. Ultimately I just want to turn off RGB (it's not really something I find interesting) but am willing to test whatever to help get it supported.
Probably similar to issue #458 (closed)
