MSI has started rolling out its latest AMD AGESA 1.2.0.2 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 1.2.0.1 which was released in a BETA variant last month.

The AMD AGESA 1.2.0.2 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 1.2.0.2 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 1.2.0.1 Patch A BETA BIOS to address the issues but the 1.2.0.2 patch is the official release.
