We must distinguish bitween driver and source.

Logitech USB Video Camera,   Version:  5.4.4.1005
Microsoft WDM Image Capture (Win32),   Version:  5.0.2195.3649

are two drivers, the first one from Logitech  the second from Microsoft.
changing the driver dont't affect the video source.
the only way that I found to change the  video source is to use
capDlgVideoSource(), but this is a dialog window, I need to do this by the
code.
May be that multimedia function don't implement the specification of twain
drivers?
