MdeModulePkg/UsbBusDxe: BOS Descriptor Check for SS Devices
Some SuperSpeed-capable devices may fall back to High-Speed
mode and cause subsequent commands to fail.
[Suggested Solution]
Check the BOS descriptor to verify SuperSpeed support and
trigger a port reset if needed to re-enumerate the device
properly.
