the id pin of usb receptacle is very connected to twl chip
i use a modified uB to A adapted during my tests
you can see orange a jumper and i can replace it with resistors
twl chip have inside comparator sensing 0, 100k 200k 400k resistor between id pin and ground ( old ? charger specs ?! )

tear id to ground switch to a_idle as expected
