I guess it could be the diode for USB power on the Pico. It actually wasn't as highly rated as it could have been (it'll be fixed on the 1v4 revision when that comes out), so it might be just on the edge when it comes to getting power off of USB.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Interesting - thanks for letting us know!
