USB 2.0 supports both High-speed, Full-speed and FullLow-speed transfers and is compatible with both host and device configurations. USB On-The-Go (OTG) extends the capabilities of USB 2.0 by enabling devices to dynamically switch between host and peripheral roles as needed. Note that C3V-W only supports SRP and HNP, and does not supports ADP.
