C# to VB.NET conversion

Can anyone translate the following to VB.NET
BOOL SetupDiEnumDeviceInterfaces(
  HDEVINFO DeviceInfoSet,
  PSP_DEVINFO_DATA DeviceInfoData,
  const GUID* InterfaceClassGuid,
  DWORD MemberIndex,
  PSP_DEVICE_INTERFACE_DATA DeviceInterfaceData
);

My declaration is giving me a PInvoke error.
  Public Declare Function SetupDiEnumDeviceInterfaces Lib "Setupapi.dll" Alias _
           "SetupDiEnumDeviceInterfaces" (ByVal DeviceInfoSet As Int64, _
           ByVal DeviceInfoData As IntPtr, ByVal InterfaceClassGuid As IntPtr, _
           ByVal MemberIndex As Int32, ByVal DeviceInterfaceData As IntPtr) As Boolean

As the referenced website indicates, the function is not working. Still unanswered.

This should do it...

    Private Declare Auto Function SetupDiEnumDeviceInterfaces Lib "setupapi.dll" ( _
        ByVal DeviceInfoSet As IntPtr, _
        ByVal DeviceInfoData As IntPtr, _
        ByRef InterfaceClassGuid As Guid, _
        ByVal MemberIndex As Integer, _
        ByRef DeviceInterfaceData As SP_DEVICE_INTERFACE_DATA _
    ) As Boolean

Here is an example of it in use

        Dim DiskGUID As New Guid(GUID_DEVINTERFACE_DISK)

        ' We start at the "root" of the device tree and look for all
        ' devices that match the interface GUID of a disk
        Dim h As IntPtr = SetupDiGetClassDevs(DiskGUID, 0, IntPtr.Zero, DIGCF_PRESENT Or DIGCF_DEVICEINTERFACE)
        If h.ToInt32 <> INVALID_HANDLE_VALUE Then

            Dim Success As Boolean = True
            Dim i As Integer = 0
            While Success
                ' create a Device Interface Data structure
                Dim dia As New SP_DEVICE_INTERFACE_DATA
                dia.cbSize = Marshal.SizeOf(dia)

                ' start the enumeration
                Success = SetupDiEnumDeviceInterfaces(h, IntPtr.Zero, DiskGUID, i, dia)
                If Success Then
                    ' prepare a Devinfo Data structure
                    Dim da As New SP_DEVINFO_DATA
                    da.cbSize = Marshal.SizeOf(da)

                    ' prepare a Device Interface Detail Data structure
                    Dim didd As New SP_DEVICE_INTERFACE_DETAIL_DATA
                    didd.cbSize = 4 + Marshal.SystemDefaultCharSize ' trust me :)

                    ' now we can get some more detailed information
                    Dim nBytes As Integer = BUFFER_SIZE
                    Dim nRequiredSize As Integer = 0
                    If SetupDiGetDeviceInterfaceDetail(h, dia, didd, nBytes, nRequiredSize, da) Then

                        ' OK, let's get the Device Number again... this time using
                        ' the device's "Symbolic Name".  If the numbers match, we've
                        ' found the one we're looking for.
                        If GetDeviceNumber(didd.DevicePath) = DeviceNumber Then
                            ' Do something here
                            Exit While
                        End If
                    End If
                End If
                i += 1
            End While
        End If
