While I dislike older FTDI products because of the poor USB protocol
they use, I was happy to see that the FT600 does everything right,
when I looked at it some time ago. I still haven't used it, but would
like to.

That's no problem. It would be easy to write some software for them.

They do have two GPIO pins, GPIO0 and GPIO1, but some software
configuration is required for them to be used as such.

The FT600 fits very well into that model.

If the Nexys FT2232H is too slow or Vivado too clumsy with USB (see
my other mail about Nexys debug communication) then I'm happy to work on
an FT600 solution instead. The FMC boards are 50-60 ¤ at Digi-Key, not bad.
