Let's start over.
That's not gonna work for me, because I want to pull power off of the Power Supply Module, to create a bus for everything
What you have is a voltage regulator board, which takes power from somewhere else, and provides 3.3V and 5V outputs.
Use those 3.3V and 5V outputs as you see fit. To power the Adafruit Huzzah via the USB connector of that voltage regulator, do exactly what you are doing now. You can also cut that USB cable, take the piece that connects to the Huzzah, isolate the 5V and GND leads, and connect them to the 5V and GND terminals of the voltage regulator.
Good luck with your project.
