OK, by using iso with altsetting=3 I get a bit over 6Mb.  The difference
is that altsetting 3 has a max packet size of 960, while altsetting 2
(the default right now) has a max packet size of 640.  Now, while I
could (and probably will) just change the default altsetting to 3, I'm
thinking that maybe the choice of altsetting should depend on the line
speed - any opinions?
