EFI_DEVICE_PATH_PROTOCOL ACPI_HID_DEVICE_PATH::Header

UINT32 ACPI_HID_DEVICE_PATH::HID

Device's PnP hardware ID stored in a numeric 32-bit compressed EISA-type ID. This value must match the corresponding _HID in the ACPI name space.

UINT32 ACPI_HID_DEVICE_PATH::UID

Unique ID that is required by ACPI if two devices have the same _HID. This value must also match the corresponding _UID/_HID pair in the ACPI name space. Only the 32-bit numeric value type of _UID is supported. Thus, strings must not be used for the _UID in the ACPI name space.
