I was able to directly connect D-/D+/GND/GPIO to the usb port on the XV and enable/disable power in order to kill the USB connection. I can now do a clean, set the GPIO, and it is on it's way, without needing a relay.
I also found a 3.3V in the XV to power the Omega2+ in the ribbon cable to the LCD. I was worried that it would turn off when the LCD times out, but appears to be constant voltage.
The Omega2+ is now powered by and controlling XV. Any suggestions for soldering on the wires to the XV? I'm using the USB plug now, and saw that some folks where soldering onto the "top" of the board, but not sure how to find the right points. I'm thinking to flip it over and solder onto the back of the board were I'm more confident about which pin is which.
