And also for those that are curious about these boards. The lines the USB cable carriers would be the 2 differential serial data pairs, total 4 wires from pins 14 & 15 on B side of edge connector and pins 16 & 17 from A side of edge connector, for the TX and RX signals. If you are curious about any of the ICs on the x16 boards, since the ribbon cable style extenders have all pins (with exception of 12 V and/or ground for the separated versions) connected, these will automatically provide all JTAG and 3.3V lines. Since this USB style one does not have these lines, the  black IC on the board is the 3.3 V voltage regulator which receives its power form the external 4 pin molex connector, which has a 12V and a 5V line on it along with 2 ground/return lines. The capacitors are used for any noise cancellation/stabilization of the power lines. And since the JTAG is not used for our needs, we can just scrap them...
