I also ordered the NZXT Hub and indeed, no flickering LED's and USB disconnect/connects anymore, nice!

Can you post a link to this NZXT hub? Is it this one? [ame= ] [/ame] My setup is almost the same and same problem: Asus Prime X570 Pro Ryzen 9 3900X 4x8GB Corsair Vengeance White RGB Pro Corsair H100i RGB Platinum Corsair RM850x PSU White Lian Li PC-O11 Dynamic Window White 9x LL120 RGB White (2x Corsair RGB fan hub) 1x Commander Pro

Same problem here with Asus Prime X570-Pro, Commander Pro, 9 LL120 Fans and 2 Lightning Node Pro. Random (every ten minutes or so) USB disconnect/connect sound and flickering LED's. So there's no fix yet? Did someone had a reply or updates from Asus/Corsair?
