Hi,
The driver of a USB device is easily found looking at
/lib/modules/`uname -r`/modules.usbmap
So, your driver is gspca_zc3xx. 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.
