    User32.DeviceInfo di = new User32.DeviceInfo();
    di.Size = Marshal.SizeOf(typeof(User32.DeviceInfo));
    User32.GetRawInputDeviceInfo(device.hDevice, User32.RIDI_DEVICEINFO, ref di, ref size);

    User32.DeviceInfo di = new User32.DeviceInfo();
    di.Size = Marshal.SizeOf(typeof(User32.DeviceInfo));
    User32.GetRawInputDeviceInfo(device.hDevice, User32.RIDI_DEVICEINFO, ref di, ref size);
