Per a user post on Reddit, AMD has been giving out some advice on how to tackle the current USB issues with Ryzen 3/5000 series chips on the 4/500 motherboards. Somewhat unsurprisingly, the advice mimics much of what individual uses have reported doing to address the issue via C-States in the BIOS, as well as manual configuration of PCIE 3. Here’s AMD’s advice:
Based on user feedback we have received; the suggestions below could improve or resolve general USB device stuttering issues.
- Verify that your motherboard is updated to the latest BIOS version and configured using optimized/factory default settings. Check your motherboard manufacturer’s website for BIOS update and download instructions.
- Check if your Windows 10 is on the latest build and fully up to date. For information on updating Windows 10, please refer to Microsoft article: Update Windows 10
- Ensure that the Ryzen chipset driver from AMD is installed and up to date. Latest Ryzen chipset driver version is 22.214.171.1241 and can be download here.
If you continue to experience USB connectivity problems after following the suggestions above, you may consider using either of the following workaround:
- Set PCIe mode from Gen4/Auto to Gen 3 in the BIOS
- Disable Global C-State in the BIOS.
These settings are found in the BIOS. Please refer to the motherboard user manual if more information is needed.
