Hi all,
    I've downloaded the 2.5.45 kernel and the modules I tried on OV511 cam
as follows.
     #usbcore
     #uhci-hcd
     #videodev
     #ov511
   But I got a error message as follows when plugging in OV511 cam.
   What's wrong? I have no idea. :<
   Any help is appreciated.
Best Regards,
             Joseph(@@)
