Posted this on another thread but this one seems like the most comprehensive thread going.
Same issues here.
Setup:
Asus Prime X570 Pro
Ryzen 9 3900X
4x8GB Corsair Vengeance RGB Pro
Corsair H115i Plat (Replaced ML 140's with LL 140's)
Corsair RM850x PSU
Corsair RGB Strips
Corsair 680x Case. 3 LL120's on the front, 3 LL140's on bottom/rear. Power connected to Corsair Commander Pro. RGB is connected to a Corsair RGB fan hub.
When the H115i is plugged into the Commander Pro it is not recognized. Lighting Node Pro also Not recognized when plugged into CoPro.
ALL USB devices disconnecting at random intervals. This sucks especially while gaming because all control is lost for about 2 seconds.
I even have tried connecting CoPro, RGB Lighting Hub, and Lighting Node Pro power on 3 separate Sata power rails on the PSU in case something was drawing too much power and it still happens. As others have said this seems to be happening on ASUS boards and primarily the Prime Pro. I see hundreds of these posts and I can't tell if it's an ASUS issue or a Corsair issue. Or even what the exact issue is...
I really bought into this ecosystem and is the ONLY fix going to be buying a different motherboard brand like MSI or Gigabyte?
I ordered the NZXT hub because that seems like a good temporary fix but I think the larger issue needs to be addressed here.
