It is quite sure that its firmware is different in your webcam. To know more, you should examine USB traces done with some other driver (ms-windows - the scripts I use to translate these traces for gspca are in my web site)... -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
