AMD believes it has isolated the reason for its persistence USB issues with Ryzen 3000 and Ryzen 5000 CPUsIt is scheduled to roll out an update to its partners in the motherboard next week. It should mean that the likes of Asus, Asrock, Gigabyte, and MSI can start integrating patches into their boards, bringing down updated BIOSes as early as April.
I took AMD to r / AMD subreddit to I thank this community To help her identify the problem and she thinks the AGEAS 184.108.40.206 update will solve several issues, including USB port leak, USB 2.0 audio cracking, and USB / PCIe Gen 4 exclusion.
There are no details on how the fixes will work, or what the actual root cause is, but at least AMD accepts that the problems are real, and not just on the minds of its users. It’s also worth noting that this didn’t affect everyone, so don’t panic if you don’t spot anything on your own.
If you are experiencing USB intermittent issues, the temporary solution that seems to be working the most is to downgrade support for PCIe 4.0 motherboards to PCIe 3.0. Not perfect, but at least it means your device should actually work. You will find the settings for this in your BIOS.
While you are setting up BIOS / UEFI, disabling global C-States is also known to help, so it might be worth clicking on this key. Once BIOS updates appear, you can return these settings to their normal settings.
