B550 Steel Legend

I've tried the latest merge for the USB Asrock B550 controller under Windows. The Windows 64 exe will start and see all my lights, but not let me control any. The Windows 32 exe will start, works properly with the lights, but will eventually just close and not run again until I reboot. I am using the polychromeusb_merge branch.

I have tried with and without the Asrock polychrome software installed. I tried the latest version, 2.0.62 and the beta 2.0.63.
