Last Updated: 11/05/2012
Version: **
AN74505 describes how libusb-1.0 can be used to develop USB host application (Cocoa Application) on MAC OS X 10.6/10.7 for Cypress EZ-USB® FX2LP™ products. This includes step-by-step procedure for developing a host application to communicate with FX2LP products. Here, a bulkloop host application is demonstrated using a bulkloop firmware.

Introduction

AN74505 describes a host application built on the MAC OS platform that uses libusb. The host application (Cocoa Application) communicates with the BULK IN and BULK OUT endpoints of FX2LP, using the interfaces provided by the APIs of libusb. This host application implements the transfer only with devices that pass the particular VID/PID(=0x04B4/0x1004) identification.

Cypress also provides a Cypress SuperSpeed Suite for MacOS platforms, which includes a Cypress API wrapper based on LibUSB. The Wrapper library for MacOS can be downloaded from this link http://www.cypress.com/?rID=57990
