USB Host V2.0
The USB V2.0 full-speed provides communication services between host and attached USB
devices. Each device is offered with a collection of communication flows (pipes) associated with
each endpoint. Software on the host communicates with a USB device through a set of commu-
nication flows.
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:
Data Flow: Control Transfer
Data Flow: Bulk In Transfer
Data Flow: Bulk Out Transfer
