Can anyone help me? Indeed, the 2 modules videodev and v4l1_compat must be loaded prior to load first gspca_main and then gspca_zc3xx, as shown by lsmod (below). Usually, insmod is not directly used. You must use modprobe which looks at the symbols and loads the required modules. > On Sat, Sep 12, 2009 at 11:54 AM, Jean-Francois Moine > <moinejf@xxxxxxx>wrote: > > > > So, your driver is gspca_zc3xx.
