Boron not powering up

I’m having some odd behavior with a Boron. It’s on a Ethernet Featherwing with 2 Adafruit Latching Mini Relay FeatherWings, and a Adafruit FeatherWing 128x64 OLED. Everything runs perfectly fine when running from the USB port on my computer. But when I try and power it using 5V into the VUSB pin, the device just sits there with the charging LED on. But it will start up and function normally if I press the Reset button. Is there some sort of signal I need to kickstart the device when using external power?

Hi @awentzel , feel free to log a ticket at support.particle.io so we can look further.
