USB Host V2.0
A communication flow is carried over one of four transfer types defined by the USB device.
Each transfer results in one or more transactions over the USB bus. There are three kinds of
transactions flowing across the bus in packets:
1. Setup Transaction
2. Data IN Transaction
3. Data OUT Transaction
Data Flow: Control Transfer
Data Flow: Bulk In Transfer
Data Flow: Bulk Out Transfer
