KB5121003 breaks AMD X470 USB xHCI: DRIVER_POWER_STATE_FAILURE 0x9F

I would collect the minidump from `C:\Windows\Minidump`, export the System event log around both reboots, and save Device Manager screenshots for the AMD xHCI controller and USB Root Hub. Since moving devices to another port helps some users, keep the current working port layout documented and avoid repeated uninstall/reinstall cycles until you have a dump. Also check the ASUS support page for the exact X470-F BIOS and chipset package level, then include those versions in Feedback Hub. For Microsoft, the strongest report will show: working before KB5121003, failing after the second servicing reboot, affected PCI instance ID, and whether uninstalling the update changes anything.
