USB4 Systems USB3 over USB4 Tunneled Protocol Mapping Support

Verifies that USB4 systems support USB3 over USB4 tunneled protocol mapping.

Description

Systems with USB4 host routers must support _DSD on the USB4 host router device or the _DSD ACPI method, as defined in ACPI Interface: Device Specific Data (_DSD) for PCIe Root Ports, to map tunneled native protocol ports (USB3) to the correct USB4 host router. This enables Windows to enumerate the correct dependencies between the tunneled protocols and the USB4 host routers on the system.
