USB 3.0 - Device Driver Understanding, Feature Enhancement and Bug Fixing

Abstract

USB (Universal Serial Bus) is a standard that defines the cables, connectors and communication protocols used in a bus for connection, communication, and power supply between Computer and Electronic Devices. USB 3.0 is the second major revision of the Universal Serial Bus (USB) standard for computer connectivity. USB 3.0 adds a new transfer mode called "Super-Speed," (distinguishable from USB 2.0 by either the blue color of the port or the initials SS) capable of transferring data at up to 4.8 Gbit/s - more than ten times as fast as the 480 Mbit/s top speed of USB 2.0. This is an IP Project in which the Device Drivers for USB 3.0, that support Mass Storage Function, HID Function and Video Function, are to be made. The embedded platform used for this Project is XIlinx Zynq ZC02 Board. Enumeration will be happened based on which Endpoint is Enabled - Bulk Stream, Isochronous, Bulk and Interrupt. Host PC will show Captured Frames by camera module with Transfer Data Rate information. In this the Zynq Board operates as a USB Camera attached to the PC. Similarly in the Case of HID and Mass Storage, the Zynq Board operates as a Keyboard and Mass Storage Device respectively.
