Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Usually they're all required to support your camera. gspca_main is probably the main driver, but this may support many models, so gspca_zc3xx is probably a plug-in to gspca_main that supports your camera specifically.
A framework called v4l(video4linux) is used by most applications to support video capture devices.
videodev & v4l1_compat are used by Linux to create the v4l video device so that it appears as a webcam.
I cam to know that i need the other two modules to be installed to work this module..ie "videodev" and "v4l1-compat"...so i copiled that modules too...but i am getting the following error..
I compiled all the required modules...ie gspca_main, gspca_zc3xx, v4l1-compat. But i am not getting this "videodev" module..I dont know why...

Insmod is working fine. But modprobe is not working properly..I know modprobe will install all necessary dependent modules. But in this case all dependent modules are already installed...But i dont know why its happening here..Please help me..see below
You are loading the module directly from that directory. To use modprobe & to ensure correct operation, you need to copy the .ko files to the appropriate location for kernel modules.
