Then, this module uses the gspca framework, i.e it calls functions of the module gspca_main. This last one calls functions of the common video module videodev. Then again, if v4l1 compatibility is enabled, videodev calls functions of v4l1_compat. lsmod shows all that directly: Module Size Used by gspca_zc3xx 55936 0 gspca_main 29312 1 gspca_zc3xx videodev 41344 1 gspca_main v4l1_compat 22404 1 videodev Regards. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
