AMD's board partners have started rolling out the AGESA 1.2.0.1 Patch A BIOS Firmware for X570 & B550 motherboards, offering improved Ryzen 5000 CPU compatibility & also including fixes for USB issues that several users were facing.
AMD Board Partners Out AGESA 1.2.0.1 Patch A BIOS Firmware To USB Compatibility Issues on X570 & B550 Motherboards, Also Offer Improved Ryzen 5000 CPU Support
AMD was meant to release its AGESA 1.2.0.2 BIOS Firmware to address the USB connectivity issues faced by several users however, it seems like the company has fast-forwarded the release with the AGESA 1.2.0.1 Patch A BIOS Firmware which is currently being offered by two motherboard makers, MSI & ASRock. The AGESA 1.2.0.2 BETA BIOS Firmware was also expected to launch in early April & it looks like some board makers weren't exactly happy with the timeframe it would take to release a fix for the intermittent USB issues that plagued the AMD Ryzen 5000 (X570 / B550) platform.
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
