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?
