Cube Orange USB dropping when powered by brick

I have a Cube Orange that loses the USB connection when I plug in the power brick harness. I checked the brick voltage and it is spot on. Interesting thing: the USB issue happens with my MacBook running windows 10 and not my Dell running windows 7. Another note: all of my other Cubes have no issue with this same MacBook. This is exclusive to this particular Cube Orange and ADSB Carrier combination. If I unplugged the Power brick harness, the USB worked again. Also to note: this particular Cube had an IMU resetting periodically. Though I just returned the unit to IRLOCK for exchange, I am curious what may have been wrong.
