[WinForms] USBカメラの列挙

var searcher = new ManagementObjectSearcher(@"SELECT * FROM Win32_PnPSignedDriver WHERE DeviceID LIKE 'USB%' AND DeviceClass = 'Camera'");

foreach (var device in searcher.Get().Cast<ManagementObject>().OrderBy(n => n["PDO"]))
{
    Debug.WriteLine("-----");
    Debug.WriteLine(device.GetPropertyValue("FriendlyName"));
    Debug.WriteLine(device.GetPropertyValue("DeviceClass"));
    Debug.WriteLine(device.GetPropertyValue("DeviceID"));
    Debug.WriteLine(device.GetPropertyValue("PDO"));
    Debug.WriteLine("-----");
}

※「Video Capture Device ID」(index)は、PDOが小さい順に振られると思っていますが、完全には調べ切れていません...
