Universal Serial Bus System Architecture

It isn't the first book I read on USB. But it's the __first__ very good book I read on USB. I suggest to everybody "read this book! it's the only thing you need"

I was handed the task of testing a USB port on an embedded system. I decided to port linux code (usb-uhci) to the embeddedplatform and this book provided a handy reference to fill in the cracks. I did not read it from cover to cover but for what I used it for ( hey, what the hell is that? )it was excellent.

I don't recommend this book for someone who has no idea what USB is, but its really useful if you need to refer to something when your working on a project. A lot of times when I need to know the definition of a word, or maybe the purpose of a certain byte in stream, it comes in handy. It also gives real-life examples for different areas fo the USB spec. (ex: usb class, subclass ID's) which helps.

A MUST... In my search for books on USB development, I came across this one... It provides you with an allround experience on USB-spec. 1.0, and gives you the background information needed to develop on the USB. It does not focus on how to write a device driver, though. But very very informative, well written and highly recommendable.. -- This one might be usefull too: http://www.annabooks.com/fx020020.htm this is another book on USB, written by one of the heads behind USB spec. 1.0
