Last month we wrote there are a lot of AMD 500-series chipset owners that complain about USB issues. It's unknown how widespread the issue is, but there are a lot of reports about USB devices randomly unplugging. Very annoying of course, as this takes you right out of your game or workflow.

AMD recommends disabling PCIe 4.0 or turning off global C-states

AMD is still investigating the issue. In the meantime, the company is now officially recommending a workaround that was suggested by Reddit users. Until AMD engineers come up with a fix, it's recommended to experiment with turning off PCI Express 4.0 mode or disabling global C-States:
AMD has provided some official guidance for affected users asking them to follow the solutions provided by Reddit such as disabling global C-States and switching to PCIe 3.0 mode if general troubleshooting has failed. AMD has reaffirmed that they were aware of the issue and that their engineers are actively working on a fix.
Not ideal of course, so hopefully AMD quickly figures out a fix to resolve the USB connectivity issues.
