Problem in grabing images from two web cams

Question

Hi
I am trying to modify single web cam capturing screen code into multiple web cam screen capturing. The method autoDetect() recognizes the web camera. I want to choose web cam by myself. I tried all devInfo from the list but it resulted no success. Always the first camera is selected . I use different cameras (Logitech and Genius). Please, how to detect both camera to work at the same time.
public CaptureDeviceInfo autoDetect ( )
        Vector list = CaptureDeviceManager.getDeviceList (null);
        CaptureDeviceInfo devInfo = null;
            if ( list != null )
            String name;
            for ( int i=0; i<list.size(); i++ )
                devInfo = (CaptureDeviceInfo)list.elementAt ( i );
                name = devInfo.getName();
               if ( name.startsWith ("vfw:") )
                                 break;
          ...The whole code is on: JWebCam

Here's source code I posted to capture a frame from one webcam.

Lots of people have problems with multiple cameras, something to do with the
Windows USB channels and failing to detect/select between the two.
So, capturing frames from 1 web cam is relatively straightforward, but you may have serious problems with two or more.
