USB OTG over Type-C uses the CC pins to negotiate data roles instead of the legacy ID pin. A USB-C cable with active CC logic identifies which end is the host and which is the device.

|---|---|---|---|
| A4 | VBUS | Power bus | PWR |
| A5 | CC1 | Config channel 1 for role negotiation | BUS |
| A6 | D+ | USB 2.0 data positive | BUS |
| A7 | D- | USB 2.0 data negative | BUS |
| A12 | GND | Ground | GND |
| B5 | CC2 | Config channel 2 | BUS |
