Same Problem here, my setup is:
Asus Prime X570 Pro
AMD Ryzen 9 3950x
2x8 GB Corsair Vengeance RGB PRO 3600
Corsair Commander Pro
Corsair Hydro Series H100i RGB Platinum SE (connected to the motherboard, if it is connected via Commander Pro it won't be recognized)
6x LL120 connected to Commander Pro and RGB Hub
2 Lighting Pro Strips connected to Commander Pro
Ordered an internal USB Card...will post results soon.
