Re: USB Over IP Documentation

do not create a virtual host controller, just write your own hub driver.
that way you do not have to deal with reverse engineering an interface
between the port and miniport, you just have to implement the public URB
interface and all of the various IOCTLs and QIs. no small task either
though.
