Walter,
Based on my reading of cablelist.txt from xc3prog, I believe the Nexys-4 is
set up the same way as the Digilent HS-2 dongle with a different product
id. I've gotten the HS2 to work, and I'm including the patch for that. You
should be able to use it with the Nexys4 with "cable DigilentHS2
pid=0x6010".
Let me know if it works.
