This new AGESA update mitigates the USB connectivity issues that some AMD 500-series motherboard users have reported, increasing the overall stability of AMD’s AM4 platform. 

To download these new BIOS updates, ASUS 500-series AMD motherboard series users should go to the company’s main support page (link) and select their motherboard. From there, you should be able to download the latest BIOS update for your motherboard.

   We would like to thank the community here on r/AMD 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.

AMD has prepared AGESA 1.2.0.2 to deploy this update, and we plan to distribute 1.2.0.2 to our motherboard partners for integration in about a week. Customers can expect downloadable BIOSes containing AGESA 1.2.0.2 to begin with beta updates in early April. The exact update schedule for your system will depend on the test and implementation schedule for your vendor and specific motherboard model. If you continue to experience intermittent USB connectivity issues after updating your system to AGESA 1.2.0.2, we encourage you to download the standalone AMD Bug Report Tool and open a ticket with AMD Customer Support.
