MSI Updates B550 and X570 Motherboards Fixing AMD USB Issue
Not everyone has had USB problems with AMD's Zen 3 chips, but plenty of users have experienced dropped connection for things like external cameras and DACs through to external drives.
MSI has released BIOS updates for its B550 and X570 motherboards that address the intermittent USB issues affecting Ryzen 5000 owners.
The new firmware implements the AGESA 126.96.36.199 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.
Full name of the update: ComboAM4PIV2 188.8.131.52
