IWDFDevice2::RegisterRemoteInterfaceNotification method

[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]

The RegisterRemoteInterfaceNotification method registers a driver to receive a notification when a specified device interface becomes available.


HRESULT RegisterRemoteInterfaceNotification(
  LPCGUID pDeviceInterfaceGuid,
  BOOL    IncludeExistingInterfaces



A pointer to a GUID that identifies a device interface.


A Boolean value. If the driver sets this value to TRUE, the framework notifies the driver if the specified device interface becomes available after the driver calls RegisterRemoteInterfaceNotification, and it also notifies the driver if the device interface was available before the driver called RegisterRemoteInterfaceNotification.

If the driver sets this value to FALSE, the framework notifies the driver only if the device interface becomes available after the driver calls RegisterRemoteInterfaceNotification.

Return Value

RegisterRemoteInterfaceNotification returns S_OK of the operation succeeds. Otherwise, this method returns another value that Winerror.h contains.


Your driver can call RegisterRemoteInterfaceNotification only if the callback interface that the driver previously passed to IWDFDriver::CreateDevice supports the IPnpCallbackRemoteInterfaceNotification interface.

For more information, see Using Device Interfaces in UMDF-based Drivers.


The following code example shows how an IDriverEntry::OnDeviceAdd callback function can register for notification of the arrival of a device interface.

    __in IWDFDriver  *FxDriver,
    __in IWDFDeviceInitialize  *FxDeviceInit
    CComPtr<IWDFDevice> fxDevice;
    HRESULT hr;

    // Create a device object and obtain the IWDFDevice interface.
    hr = FxDriver->CreateDevice(FxDeviceInit,
    if (FAILED(hr)) goto Error;

    // Obtain the IWDFDevice2 interface from IWDFDevice.
    CComPtr<IWDFDevice2> fxDevice2;
    if (FAILED(hr)) goto Error;
    hr = fxDevice->QueryInterface(IID_PPV_ARGS(&fxDevice2));
    if (S_OK != hr) goto Error;
    // Register for notification when a device interface
    // arrives.
    hr = fxDevice2->RegisterRemoteInterfaceNotification(&GUID_DEVINTERFACE_TOASTER,
