But the interface has expanded to support faster bus speeds, improved power delivery and management, more device classes, wireless communications, support for embedded systems that access USB devices, and more.
New and improved chips and development tools have eased the task of developing devices and the software to access them. This Fifth Edition is revised and updated throughout.
New topics include an introduction to USB 3. Much of the information in this book applies to any device hardware and host computer. The example code for applications uses Visual C. Each hub has an interrupt IN endpoint for reporting these events to the host. On system boot-up, hubs inform the host if any devices are attached including additional downstream hubs and any devices attached to those hubs.
After boot-up, a host continues to poll periodically USB 2. The host then attempts to enumerate the device by issuing control transfers containing standard USB requests to the device. All USB devices must support control transfers, standard requests, and endpoint zero. For a successful enumeration, the device must respond to requests by returning requested information and taking other requested actions.
My USB Central page has the latest versions of applications and firmware using the example code in the book, plus links to chip and other product information and much more. USB 2. However, just how much useful information any mortal who wasn't involved in writing this tome can actually glean from it without going insane is a different matter.
An excellent and highly recommended how-to guide and reference. A great job of presenting the difficult topic of USB peripheral development.
Pfalzer, Book Review of the Week, www. The author has a flair for taking complicated information and making it readable, interesting, and informative. This is the best book on the topic.
I recommend it highly. Jan Axelson has done it again. A readable and comprehensive book that covers all aspects of actually building and coding USB devices. Jan's description of building a HID-class peripheral is the best around.
This is the best, clearest, single source of USB information I've yet seen published. It's unusual to find such an easy-to-read style combined with real meat. I tell all my students that they really need this book in their library. Many books are full of things that are easy to find out, and skirt around the harder stuff, which you have to really work at. What I really like about this book is that Jan has obviously slogged at the difficult stuff as well.
USB Complete provides a great groundwork for anyone working with USB for any purpose, whether it is designing a peripheral or creating host software. This book should be read by anybody getting started with USB. See our Privacy Policy and User Agreement for details. The SlideShare family just got bigger.
