We actually _want_ the debug port support.
The EHCI/XHCI debugging stuff is separate from the whole normal USB
stack and is really designed for lower level debugging - ie, when
everything is actually busted.
Think of it as being the polled conduit for doing remote kgdb and
(hopefully, with the XHCI stuff) remote memory inspection when things
go off the deep end.
