The USB debug port requires much less support than full blown USB and so 
can be used in restricted environments. PCI seems to be going away and 
even when it is present port 80h does not always work by default, it can 
need configuring.

Support for passing POST codes or even progress strings over USB debug 
devices would be very useful indeed.
