Run Linux From USB Flash / Pen Drive

If you wanna run Linux any time, any place, any computer, try USB device. Here's what to do with popular distributions like Puppy Linux, Ubuntu, and Fedora, so you can boot up directly from your thumb drive:

Most of the time, Linux is run from either an installation on a hard drive or a live CD/DVD distribution. The first is fast, but not very portable; the second can be run anywhere you have a computer and a CD drive with boot access, but typically isn't very fast. Over the last few years, though, we've seen the emergence of something that combines the speed of a hard drive install with the convenience of a live CD: running Linux from a USB flash drive.

=> How To Run Linux From A USB Flash Drive

USB devices are quite common these days. I've digital cam, Pen drive, external hard disk, mouse and other stuff. So how do I tell what hardware is connected via USB to my Linux desktop?

lsusb is a utility for displaying information about USB buses in the system and the devices connected to them. To make use of all the features of this program, you need to have a Linux kernel which supports the /proc/bus/usb interface.

-v command option is very informative. It tells lsusb to be verbose and display detailed information about the devices shown. This includes configuration descriptors for the device’s current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communications, and chipcard.

lsusb command Examples
