worked for me.

I was handed the task of testing a USB port on an embedded system. I decided to port linux code (usb-uhci) to the embedded
platform 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.
