11.1.1 Features
11.1 Introduction
11.2 Overview
The Universal Serial Bus (USB) Host Controller enables communication to USB 2.0 low-
speed (1.2 Mbps) and full-speed (12 Mbps) devices. The controller supports three root hub
ports and complies with the Open Host Controller Interface (OpenHCI) specification, version
1.0a. (For additional information, see
The features of the USB Host Controller are:
The USB Host Controller is partitioned into the key sub blocks as indicated in
Figure 11-1
Note: The EP9301 and EP9302 processors each have 2 USB 2.0 Host ports.
Note: The EP9307, EP9312, and EP9315 processors each have 3 USB 2.0 Host ports.
• Open Host Controller Interface Specification (OpenHCI) Rev 1.0 compliant.
• Universal Serial Bus Specification Rev. 2.0 compliant.
• Support for both low speed and full speed USB devices.
• Root Hub has three downstream ports
• Master and Slave AHB interfaces
• DMA functionality
• Client Software/USB Driver
• Host Controller Driver (HCD)
• Host Controller (HC)
• USB Device.
