This driver was developed using a USB keyboard from Cherry,as indicated by the VID and PID codes. These IDs must be set for the device you intend to support. Similarly, you will need to set Class to the appropriate string for your device class.
LPC2148 USB Audio Device Example
This USB example project implements an USB Audio Device that connects via the USB interface to the PC. It may be used on the following devices:
LPC2141
LPC2142
LPC2144
LPC2146
LPC2148
An USB Audio Device (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio devices can be directly connected to the computer. This example project is designed to work with Keil MCB2140 Evaluation Board.
Refer to Running USBAudio for information on how to operate this example project.
pic mcu code:This application note describes the design and
implementation of a USB Mass Storage Device (MSD)
using a Secure Digital card, which should prove useful
to developers of USB mass storage solutions. This
application may be used as a stand-alone MSD or as a
Secure Digital/Multimedia Card (SD/MMC) reader/
writer interface.
This directory contains the memtest 8051 firmware
for the Anchor Chips EZ-USB chip.
The purpose of this software is to test the different
memory segments in the Ez-Usb chip.
This example will output the string "good" on the 7 segment
LED if the mem test passes, or it will output the first address
where the memtest fails.
This module is common to all of the Example programs
It declares the {Open, Read, Write, Close} calls for the USB device
These user-calls are translated into OS system calls
This module also contains several support routines used by all of the examples

This design package includes reference materials for creating a
USB - PS/2 combination mouse that auto-detects the interface and
configures itself to operate on the appropriate bus.

This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer
desktop motherboard. The material covered can be broken into three main categories: Board design
guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an
explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per
second on an actual motherboard. Section 7 contains a design checklist that lists each design
recommendation described in this document. High speed USB operation is described in the USB 2.0
Specification (http://www.usb.org/developers/docs.html).
