Logitech C270 installation problem solved

I looked back what did I do in the last couple of days and found that I might have forgotten to reset some configuration files after the web cam server test.  I found that I forgot to reset the start_motion_daemon to no in the motion setting.

I am a bit confused for now, because I thought the motion thing has nothing to do with Pygame, but now I know motion can at least interfere with Pygame.caamera.

Now that the test function can run to it end.  Next step is to check out where the captured image has hidden and display it. perhaps with my Win 7 Photoshop.
