It would be really convenient for me to power a 3rd party device I am using via the 1500's USB connector. I am already, however, powering the unit via VIN (from a regulated 5V switching supply) that I've mounted on my mated MKR Relay Shield board from the small proto section. I believe the documentation stated somewhere that if powering the 1500 from VIN, then it would disable the USB port. Is there a way to bypass this, or did I misinterpret?
Otherwise, I assume I am just going to have to solder a connection from 3rd party device to the 1500's pins 13/14 UART.
