WDFDevice配置

文件标识

WdfDeviceSetSpecialFileSupport(*WdfDevice, WdfSpecialFilePaging,    TRUE);  // 分页文件支持
WdfDeviceSetSpecialFileSupport(*WdfDevice, WdfSpecialFileHibernation, TRUE); // 休眠文件支持
WdfDeviceSetSpecialFileSupport(*WdfDevice, WdfSpecialFileDump,      TRUE);  // 转储文件支持
WdfDeviceSetSpecialFileSupport(*WdfDevice, WdfSpecialFileBoot,      TRUE);  // 启动文件支持

这段代码位于 USB xHCI（USB 3.0）控制器驱动中，设置这些标志后：

• Windows 会允许将分页文件、休眠文件等关键系统文件放在连接到该 USB 控制器的存储设备上
• 这对于使用 USB 外置硬盘作为系统盘或休眠分区的场景至关重要

设备名和GUID

//链接名
    status = RtlUnicodeStringPrintf(&uniSymlinkName,L"%ws%d", BASE_SYMBOLIC_LINK_NAME, instanceNumber);
    status = WdfDeviceCreateSymbolicLink(*WdfDevice, &uniSymlinkName);

    //子设备总线信息
   // Set bus information for children devices.
   PNP_BUS_INFORMATION                 pnpBusInformation;
   pnpBusInformation.BusTypeGuid = GUID_BUS_TYPE_USB;
   pnpBusInformation.LegacyBusType = PNPBus;
   pnpBusInformation.BusNumber = 0;
   WdfDeviceSetBusInformationForChildren(*WdfDevice, &pnpBusInformation);

   // Create the device interface.
   //GUID接口
   status = WdfDeviceCreateDeviceInterface(*WdfDevice,
                                           (LPGUID)&GUID_CLASS_USB_HOST_CONTROLLER,
                                           NULL);
