Ryzentosh USB problems?

Anyone else having weird or intermittent problems with Ryzentosh builds? I have a 3rd Ryzen 5 3600 plugged into an ASRock x570 Taichi board and it works great, except when I connect USB sound devices to it. The device is always detected, but often the sound will start out fine and then become horribly distorted or latent, or the sound will just not work at all. Currently I am trying to connect a Focusrite Scarlett 4i4 which shows up in System Profiler, but the Focusrite control software cannot see the device. The device works on every other real Mac and Hackintosh in my house, but this Ryzen hack.

For what it is worth, I have mapped the USB ports and renamed the controllers to avoid conflicts with the iMacPro1,1 (my SMBIOS) built-in port mapping. I have also confirmed that I am not hitting the 15-port-per-controller limit.

Any ideas?
