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.

I have a digital USB camera based on the Empia Technology 2750 (Tucsen microscope camera 1.3mp) that is giving me fits.
The info from lsusb:
Bus 001 Device 008: ID eb1a:2750 eMPIA Technology, Inc. ECS Elitegroup G220 integrated Webcam
It works with low resolutions (under 640x480) in Cheese, and when you try to use higher resolutions the picture gets scrambled. I've tried different resolutions and the funny thing is that they're all weird ones- 1024x816 vs 1024x768 (normal). Everything I've tried doesn't work- I cannot figure out how to force the driver/software to set the proper resolution for the camera.
I've tried luvcview, and it crashes. The error message is: "Init V4L2 failed!! exit fatal".
I've tried running the camera under Wine, and the software I've tried either crashes or I get "Can't add Smart Tee". I can run it with Windows XP in virtualbox, but there is a 5 second delay between making a change and the video reflecting that change (making adjustments a real headache!). It works flawlessly when I go to my Windows XP boot, but I'm trying my best go get away from Windows and stick with Linux (and Wine if I can get this to work right).
The less I have to fight with Windows, the happier I will be.
Can anyone help me with this headache? Is there some way to force the driver to have the correct resolution? Could it be a bad driver (it would have to be bad from the repository)?
