The original problem seemed to be most pronounced when customers enabled PCIe 4.0 support on their motherboards. PCIe 4.0 must be turned on to get the most performance out of current-generation graphics cards and the latest blazing-fast PCIe 4.0 SSDs, which could in some cases cause USB peripherals to act erratically or completely lose connectivity.
"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," said AMD when it announced the development of the AGESA 22.214.171.124 BIOS update back in March.
