Not as far as I've read the standard. "Speak only when spoken to"
appears to be the rule at least in 1.x and 2.x. USB OTG is a little
different in that some devices can assume either the guise of a
controller or a slave, but one still can't have multiple controllers
in a USB topology as far I know--which may well be dated by now..
