AMD has announced that it will release a beta BIOS addressing the USB connectivity issues that certain 500 Series (and 400 Series) chipset motherboard owners are wrestling with next month. Red team confirmed the news in a post on the official AMD subreddit, which noted that the relevant AGESA update, version 188.8.131.52, will be available to customers in early April. Some of the issues that AGESA 184.108.40.206 should fix include dropouts of USB peripherals and audio crackling with external USB DAC/AMP combos.
“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,” AMD wrote. “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 220.127.116.11 to deploy this update, and we plan to distribute 18.104.22.168 to our motherboard partners for integration in about a week. Customers can expect downloadable BIOSes containing AGESA 22.214.171.124 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.”
Users who continue to experience intermittent USB connectivity issues after updating their systems to AGESA 126.96.36.199 have been encouraged by AMD to download the company’s standalone Bug Report Tool and open a ticket with AMD Customer Support. AMD confirmed that it would be investigating the USB connectivity issue with 500 Series motherboards last month, which drew plenty of upvotes from affected users.
