MSI has started rolling out its latest AMD AGESA 22.214.171.124 BIOS Firmware for X570 and B550 boards which addresses several USB compatibility issues and offers better support for Ryzen 5000 CPUs. The latest AGESA Firmware is an incremental step up from AGESA 126.96.36.199 which was released in a BETA variant last month.
AMD AGESA 188.8.131.52 BIOS Firmware Now Rolling Out By MSI For X570 & B550 Motherboards, Fixes Ryzen USB Compatibility Issues
The AMD AGESA 184.108.40.206 BIOS Firmware was scheduled to roll out this month as the company had reported and it looks like MSI is the first motherboard maker to once again offer support for X570 and B550 motherboards. The AGESA 220.127.116.11 BIOS Firmware is designed to address the intermittent USB issues related to Ryzen CPUs and the respective AM4 platform. Several motherboard makers had also released the AGESA 18.104.22.168 Patch A BETA BIOS to address the issues but the 22.214.171.124 patch is the official release.
We would like to thank the community here on the AMD Subreddit for its assistance with logs and reports as we investigated the intermittent USB connectivity you highlighted. With your help, we believe we have isolated the root cause and developed a solution that addresses a range of reported symptoms, including (but not limited to): USB port dropout, USB 2.0 audio crackling (e.g. DAC/AMP combos), and USB/PCIe Gen 4 exclusion. via r/AMD
As of now, MSI is offering the AGESA 126.96.36.199 BIOS Firmware with a total of 21 motherboards of which five are based on the AMD X570 chipset and 16 are based on the AMD B550 chipset.
