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.

side usb works fine. Two usb ports on back to do not. I have done diagnostics, uninstalled drivers, etc. The computer tells me they are fine and working. It is as if there is no power going to them. No plug and play and no lcd light on my pieces that I put in, light up. I am so frustrated. My gut tells me it is programming or power. Can someone walk me thru some things? Newbie but I can get around pretty well, if someone tells me what to do.
What sort of computer is it?
Are the back ports physically connected to anything inside the case?
Do the ports need to be enabled in your BIOS?
Two useful tools: lsusb an usbview. Install and run them from the command line
how do I install and run them from the command line, in XP? Is it just the "run line" As far as what I have done already, disabled and reinstalled drivers, over and over. I tried to get the case open to see if they were connected in the back, but couldn't get a few of the screw out. The windows and toshiba diagnostics states they are there, when do just their diagnostics. thanks for the help!
At the top of this page it says "LinuxQuestions.org", because this is a site for people running linux, not windows.
You might be better off going to a windows site, if that is what you are having problems with.
But now you are here, maybe you'd like to give linux a try ?
Here's a link to a popular distro: http://kubuntu.org/download.php

A classic example of how [un]helpful Windows Device Manager is. If they were vibrating and sparking, as long as the driver is loaded Windows would still say "The device is working properly."
Seriously, though, would the back ones happen to be a PCI card that was manually installed? And if so was its driver installed instead of Windows' generic? Or is it USB 1.1 ports and your connecting a device that requires USB 2.0? That would explain the power issue.
