Lucent Technologies USS-720 Operating Systems Supported, Power Management, Installation Process

Application Note, Rev. 1	Incorporating Customer Data into USS-720
February 1999	Evaluation Kit Software Using the Build Me One Utility

Operating Systems Supported

This software runs in Windows 95, and Windows 98.

Windows 95 must actually be OSR2.1 version 1214, which contains the USB supplement and QFE. Each vendor who purchases the USB Smart Cable from In- System Design must execute an agreement with Microsoft in order to distribute the USB supplement. Microsoft may license the vendor to distribute the following files to update Windows 95 software:

1.OEMUSB.EXE version 4.03.1214,

2.DETROITR.EXE,

3.USBUPD1.EXE version 4.03.1214.

To execute a distribution agreement with Microsoft, contact Stephanie Selden at Microsoft, email sselden@microsoft.com.

Note: As of August 1998, Microsoft is no longer licensing the OSR2.1 supplement.

Power Management

The USB Smart Cable supports power management on the PC if its operating system supports the specific power management feature. The USB Smart Cable supports suspend and resume functions in all supported operating systems.

Note that OSR2.1 supports suspend and resume func- tions but there is no USB support in OSR2.1 for “0 volt suspend” in which case some PCs cut the power upon suspending. Windows 98 does support “0 volt suspend.”

USB Hardware Types Supported

The USB Smart Cable operates with all OHCI and UHCI USB controllers and hubs that are compliant with the USB Specification, Revision 1.0.

Installation Process

The software for the USB Smart Cable is loaded auto- matically by Windows PnP operation.

USBLPTx Ports

Evaluation kit version of software:

For each USB Smart Cable plugged into a host’s USB, a port will be added called USBLPTx (where x can be from 1 through 127). These ports will remain in the system with their current status if a printer is associ- ated with the port. If no printer is associated with a USBLPT port when the corresponding USB Smart Cable is removed, the port is removed from the system.

Modified version of the USS-720 software:

For each USB Smart Cable plugged into a host’s USB, a port will be added called XXXXXXx (where x can be from 1 through 127). The “XXXXXX” string is defined by the customer, for example: “LPTXYZ”.

EEPROM

Developers using the USS-720 must use an external serial EEPROM (or the equivalent) in their design and create their own hex data file for use in programming the EEPROM at their site. See the USS-720 Data Sheet and the glucent.zip file on the kit’s diskette for more information. The configuration data stored in this serial EEPROM is used by the Microsoft host software during enumeration to load the appropriate drivers. Using unique identification data in the EEPROM provides a means for the developer to ensure that only their software is loaded for use with their device.
