Query: Worthless for embedded developers

The book is clearly written to help windows driver makers build a windows USB driver for device X. If you aren't a Microsoft user or are using anything other than C#,VB this book is completely worthless. The book talks very well about the basic idea of USB, however, completely skips over the nuts and bolts. I found wikipedia provided better information on the topic. The only use I found for the book was to prop up my monitor a little higher, which is nice on my neck.
