Well yes, you can.  I don't know whether it's the case with USB in  
particular, but it's not uncommon for a specification, especially one  
written by a standards committee, to contain pieces that are just not  
efficiently implementable on any real systems.  Sometimes this happens  
from simple ignorance, but I think too often it happens as a result of  
the committee not wanting to "favor" some particular vendor who might  
otherwise have too much of a "head start."
