Unknown hardware combo I guess.I've heard of these USB issues with AMD but I've used both AM4 and AM5 extensively and I have never experienced it. What is the trigger, usually?
I had it on an Asus b550 itx board, with a 3900x. But not with a 5950x.
I actually downgraded to the 3900x. And the issue wasn't fixed by updates, in the approx 4-5 months I had that combo. So, I sold them separately.
