USB issues on B550

Hi, i own a Ryzen 3500X with a B550 DS3H , with its latest BIOS F13.

I have a RTX 2060, so no pciE 4.0 here...

But i have all sorts of USB issues, every keyboard has chattering (some usb ports more than others), every usb wifi adapter or bluetooth will randomly disconnect (in particular during heavy cpu loads or heavy storage loads).

I am at a loss here, i don't do any overclocks , everything here is at stocks speeds and features.. (Issues are appearant on Linux aswell).

At this point the CPU or Motherboard are faulty i guess , is there any upcoming AGESA update that is going to fix this pherhaps?

Have you tried turning off 'usb selective suspend'.

Re: USB issues on B550

I'm experiencing the very same problem on an Aorus B550i with a 5900x, also bios version F13; it is practically impossible to use the mouse while there is more than one peripheral connected to another usb port. I've tried all solutions present in other discussions with 0 results. This problem is present both in windows and linux (ubuntu 21.04). At the moment I've "solved" connecting the mouse to the usb typeC with a usb C docking station. Of course this is not a solution at all since I should be able to use the mouse attached to every usb port regardless the other usb are connected or not.
