For old some micro usb devices, you can wire the ID pin so it is connected to the ground pin with a resistance of something like 36.5 kΩ. When the device is in host mode and connected to a device, this would allow the android host device to receive power from an external source when it was connected to the Vbus pin.
Basically, this allowed a device to be charged, while in host mode and still be in control of the peripheral device. I believe this kind of connection was known as accessory charging adaptors (ACA).
My question is, is there an alternative wiring to this for USB-C, can I buy some sort of adaptor, or even design some sort of board myself to go between a USB-C phone and a peripheral device?
