OTG Rules

Source: S.Kumar

USB OTG describes two functions of a device.

  1. The display of OTG A and OTG B devices shows which side is the first host and which side supplies the connection power.
  2. OTG A-device supplies a power source, and OTG B-device manages power consumption.
  3. In the default connection configuration, the B-device is a USB peripheral and the A-device is a USB host.
  4. Later, the host and peripheral modes can be changed using either RSP or HNP. Due to the fact that each OTG controller performs both functions, they are also referred to as Dual-Role controllers.
