I have implemented it on Octaos,I don't use books but you can start here:
http://www.usb.org/developers/usbif
There is a forum to ask questions ,links to various resources,and also the usb specs in pdf format that i have readed many times.
In the forum there is a guy that write books about usb.
Implementing usb is not easy,usually when i ask on the forum i get this reply:
"you need to buy a usb analyzer"
In this other link there is also a example program:

I agree with octavio, books will be little help, you need the spec, and lots of time and hard work.
I worked so hard on mine, i am not going to give it away (its a key thing in a OS, as to why someone would use one hobby OS, over another), but theres alot nicer people out there that will give you bits of code, eg:
