Replying again cuz I just noticed another possible bug in usb hw.

According to usb battery charging specs, charger detection should be
done sampling capacitance on Vbus line, not putting a resistor between
id pin and ground.

ID pin is used to switch between peripheral/host roles.

Am I misreading? :-s

I'd like to have access to Neo's schematics, is it possible?
