Do you know which firmware and FPGA gateway is flashed to your device? I have a similar USB 3.0 issue not getting it to stream data properly and USB 2 is at least partially functional for me as well.
Read(64 bytes) failed
Gateware version mismatch!
Expected gateware version 2, revision 17
But found version 0, revision 0
But I don’t get this type of error message.
