JMF - how to detect second webcamera

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

I tried getting the device list on my system but the following code is not returning any devices (deviicelist is empty) ? When I look at my Device Manager on Windows7 machine, I see there is 'High Definition audio device' . Does anyone have a clue why/when would this happen ?
I have jmf installed and it is in the classpath. I also have jmf.jar, sound.jar added to my project.
CaptureDCaptureDeviceInfo di = null;
Vector deviceList = CaptureDeviceManager.getDeviceList(
                    null);
          if (deviceList.isEmpty())
               System.out.println("No Devices found");
          if ( deviceList.size() > 0 )
          di = (CaptureDeviceInfo)deviceList.firstElement();
          System.out.println("di::" + di.getName());
