        string[] deviceIDs = new string[cDevices];
        devMgr.GetDevices(deviceIDs, ref cDevices);

        for (int ndxDevices = 0; ndxDevices < cDevices; ndxDevices++)
        {
            Console.WriteLine("Device[{0}]: {1}",
                    ndxDevices + 1, deviceIDs[ndxDevices]);
        }
    }
    else
    {
        Console.WriteLine("No WPD devices …
