By the way, USB3 is now hitting the mainstream, with PCI boards,
motherboards, disk drives and USB sticks from all the major vendors.
It provides a significant bandwidth boost over USB2 (it's designed for
3Gbits/sec, both ways simultaneously). This would be very useful to
any newly designed USRP-like device.
I agree that it's worth considering, I think it has extended range as
well. Competing very firmly with
GiGe!
I haven't investigated what chips could replace the EZ-FX2 in a USB3
USRP. Oddly, the Cypress site seems to know nothing about USB3
devices!

Yes, I found that same thing. Seems odd that Cypress wouldn't be one of
the front-runners for
USB-3.0.
I will point out that one of the enticing things about 1GiGe is that you
can run it over extended distances.
Which for me is very interesting, since you could put a receiver at
each antenna (think Alan Telescope Array),
and haul signals back via 1GiGe. With USB-2.0, you can't do that
without a funky device like the ICRON Ranger
series (which inside, just re-packages USB-2.0 over 1GiGe, as far as
I know).
