MSI has released BIOS updates for its X570 and B550 motherboards that address the intermittent USB issues affecting Ryzen 5000 owners. The new firmware implements the AGESA 184.108.40.206 update AMD released to manufacturers just over a month ago, and while these BIOS updates are officially still in beta, reports have been positive so far.
Not everyone has had USB problems with AMD’s Zen 3 chips, but plenty of users have experienced dropped connection for things like external DACs and cameras through to external drives.
The stop-gap suggestion from AMD was to drop the PCI Express connectivity from 4.0 to 3.0 until the patch was released, which was particularly annoying for anyone using a next-gen NVMe PCIe 4.0 SSD. This patch should offer a more long-term solution.
MSI has been releasing updates for its motherboards since April 8, and now has 21 of its motherboards covered. Five X570 and 16 B550 boards have received the much-needed fix to address USB problems. You need to check the update includes the line: “Update to ComboAM4PIV2 220.127.116.11”.
