Scatter-gather with chunks of multiples of endpoint size wouldn't be a
problem for UHCI.
OHCI I imagine would need some work but it should be done.
If the chunks aren't endpoint sized, then you have to do lots of buffer
management and it's probably not worth the effort.
The interface would take some thought.
