AMD has responded to the USB connectivity issues that have recently plagued the Ryzen platform and is issuing a BIOS patch to fix the problem in April. AMD has announced a fix for the widely-reported USB connectivity issues that have impacted systems with Ryzen processors via a Reddit post.
AMD has announced that it will release a new bios patch in April called AGESA 1.2.0.2. The fix for the problem comes after AMD acknowledged reports of the issues last month and asked users to help it pinpoint the source of the problem by submitting detailed logs.
AMD will be releasing the AGESA 1.2.0.2 BIOS to motherboard vendors in a week. Downloadable beta BIOSes with the patch will land in early April. Fully-validated BIOS versions with the fix will most probably arrive shortly after that.
The issues seemed confined to Ryzen 3000 and 5000 series CPUs in 500- and 400-series motherboards (i.e., X570, X470, B550, and B450) and consisted of random dropouts for USB-connected devices. The complaints were across different types of USB devices like keyboard connection drops, issues with VR headsets, external storage devices, and others.
AMD posted the following statement regarding the issue.
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.
We will have to wait for the BIOS to come out to see if the issue is really resolved or not.
