Incorporating Customer Data into USS-720 Evaluation Kit Software Using the Build Me One Utility

Introduction

Using the Build Me One utility found on In-System Design’s web site, the USS-720 Evaluation Kit soft- ware can be modified to include data specific to a customer’s USB peripheral. This document describes the components, customization data, and other general topics related to the free software provided by Lucent Technologies and In-System Design in support of the USS-720 Instant USB™ device. See the instructions under Customer-Defined Data below for information on obtaining the free software.

Software Components

The files obtained by using the Build Me One utility are the software necessary for standard PnP installa- tion and operation of the USS-720-based USB Smart Cable. This software consists of:

1.

Class Installer,

xxxxxxCI.DLL;

2.

WDM device driver,

xxxxxxSB.SYS;

3.

Port monitor installer,

xxxxxxIN.DLL;

4.

Port monitor,

xxxxxxMN.DLL;

5.

Install file,

xxxxxxSB.INF;

The six-character “xxxxxx” strings are defined by the customer. (Refer to ‘Driver Name’ information in the Customer-Defined Data section below.)

Example: If “XYZPRT” is the ‘Driver Name’ defined by the customer, then the Class Installer software file would be named XYZPRTCI.DLL.

Installer checks that all required components are installed for OSR2.1 systems (Windows 95 with the USB supplement and QFE).

If the Class Installer finds the operating system is correct, the device driver and port monitor are installed. If the Class Installer finds the operating system either does not correspond to the software or the operating system does not have all required components, an error message is displayed.

WDM Device Driver

The device driver for the USB Smart Cable follows the Windows Driver Model specification. Note there are different binaries for Windows 95 and Windows 98 as different libraries are linked. Note that the supplied software will work only with printer drivers that use the Windows spooling system to interface with the USS-720 USB port monitor.

Port Monitor

The port monitor, developed by In-System Design, is responsible for the communication between the Windows spooler and a printer. This port monitor enables printing from Windows applications using the USB Smart Cable. The port monitor controls the I/O port to which the physical printer is connected and is responsible for the communication channel between the spooler and the printer.

Class Installer

The Class Installer checks that the operating system version is compatible with the USB Smart Cable soft- ware being loaded. This is necessary as there are two different binary versions of this software, one for Microsoft Windows* 95/OSR2.1 and one for Microsoft Windows 98. Furthermore, the Class

Install File

The install file is modified to match the information provided by the customer. The information in the external EEPROM is used during the Plug and Play process to load the correct device driver.
