Four weeks after the stability issues in the USB connections of motherboards with AMD 500 series chipsets became known, the company revealed on Reddit that they have already managed to identify the problem, and it will be fixed by launch of a new microcode, AGESA 22.214.171.124, which unfortunately will not arrive until the beginning of April, 2021.
Although AMD indicated that they will release the microcode next week, but it has to be the motherboard manufacturers themselves who integrate it in BIOS update, which adds additional time for its deployment.
“We would like to thank the community here at r / AMD for their help with logs and reports as we investigate the intermittent USB connectivity they complained about. With their help, we believe we have isolated the root cause and developed a solution that addresses a reported number of issues, including (but not limited to): USB port dropping, USB 2.0 audio crackle (e.g. DAC / AMP combos), and USB / PCIe Gen 4 exclusion.
AMD has prepared AGESA 126.96.36.199 to roll out this update, and we plan to roll it out to our motherboard partners for integration in about a week.Customers can expect downloadable BIOSes containing AGESA 188.8.131.52 to begin beta updates in early April.
The exact update schedule for your system will depend on your vendor’s testing and deployment schedule and the specific motherboard model.
If you continue to experience intermittent USB connectivity issues after updating your system to AGESA 184.108.40.206, we encourage you to download the standalone AMD Bug Report Tool and file a ticket with AMD customer service.
