@meeotch I checked my email archive. Time flies! Turns out I researched this back in late 2015! Sorry about the time error. The situation is probably the same today though. And two USB devices would most likely give you trouble with timing, unless the devices have word clock inputs so you can clock them from the same reference. The offer from Vincent Brient actually included re-programming of the FPGA in the d1 by the way.
