I have my Teensy 4.1 powered by an adafruit powerboost 500 with a lipo. I want to be able to charge the battery and reprogram the teensy over the same USB port.
What I've done:
Charging and powering the Teensy works fine, but plugging everything into a PC gives me "Device not recognized". Using the Teensy directly with the PC works, I've checked continuity on every line, and everything I've looked at suggests this should work... but it doesn't.
Anyone know what I'm doing wrong? or how to fix it?
Thanks.
