This chapter describes the software structure of the USB Host Component and explains its use for creating an USB Host application.

The USB Host Component simplifies software development of microcontroller systems that can communicate with USB Devices.

Attributes of the USB Host Component:

Complies with the USB 2.0 specification.
Support for HID, MSC, CDC, and Custom USB Device Classes to be connected to the USB Host.
Support for control, interrupt and bulk transfer types.
Explains how to Create a new application from scratch.
Provides Examples implementing different USB Host use cases.

RTE Components

The following picture shows the relationships of the RTE Components with the microcontroller's USB Host peripheral (USB Controller). RTE Components provide configuration files and user code templates.

Configuration files configure the RTE Components, hardware interfaces, memory resources and USB Host parameters.
User code templates provide the skeleton for implementing support for different USB Device classes.
