I believed a lot of people already know this issue but AMD still don't have any fix on the issue, which causing a lot of pcs' basically unusable as most or even all of the USB ports are not working, both internal or external are affected.
For my issue, I RMAed a TUF B550M-Plus and the new one has the same issue. Tried every BIOS update and they did not fix it. Tried disabling C-state, forcing it to run in PCIE Gen 3 instead of Gen 4 also did not fix. All of the possible fix listed on reddit (https://www.reddit.com/r/Amd/comments/kbr6zl/usb_issues_on_b550x570_motherboards/) did not help at all.
I'm wondering whether anyone in this community has any recommendation on how to fix the issue as I'm running out of ideas now.
If the issue still exist and AMD don't have a fix for it at the end of the January, I'll tell every customer to avoid AMD products at all cost.
