I attended a seminar at http://www.netseminar.com over the Internet on this
subject back in June.  It is only an Introduction but there was some good
information about design.  You may have to register with them to access the
archives of NetSeminars.  There is no cost to register and is done online.
I am not affiliated with Netseminar in any way.

Subject:  [TN] USB Port Specs




Hello

I would greatly appreciate any assistance in finding a power Spec for
the USB Port. I have a client who is interested in developing a product
to interface with this port. What amount (voltage and current) of power
can be supplied through this port?
