This is about the best I could do:
<A HREF="http://www.euro.dell.com/downloads/global/vectors/usb.pdf" target="_new">Advances in USB technology</A>
<A HREF="http://www.geocities.com/~budallen/usb.html" target="_new">The Complete Guide on USB</A>
I was able to locate a great deal of information that talks about USB supporting hot-plugging, but not much beyond that.
Good luck!
