Use of this mode requires a special comparator to detect the special resistor on ID pin, which might be not supported on every portable device. And the function must have proper firmware support to turn the power role while keeping the host functionality. | |

I just sifted through the docs because I didn't trust Wikipedia's implicit data on which of the three resistances I should use. Here you can find the official Battery Charging v1.2 Spec and Adopters Agreement: usb.org/developers/docs/devclass_docs In this case you want 124kΩ, because you want the OTG device (=tablet) to be the A device (=host).
