As I anticipated, there must be something in place that I am not aware of for pwr. I need to study this more, but this essentially it is a spec from USB 2.0. I guess if I want up to 750 mA I need to use USB 3.0.
On another note, I was following the post that you shared to me which overlaps with my post and I was wondering by doing this does it read the preconfigured pin_arduino.h file? Because the my_custom_rp2040_board.json file is generated before editing or adding to the pin_arduino.h file.
If not, is the only way to get the pin_arduino.h to preconfigure my pins is to PR the changes to: https://github.com/earlephilhower/arduino-pico
