Plug and Play

The Plug and Play capabilities of the supplied software are limited to the enumeration of the USS-720 deviceonly.

Port Creation

The USS-720 software driver supports printing via the creation of a port named USBLPTx, where x is an integer between 1 and 127. Each instantiation of the driver will generate another USBLPTx port. If two developers both have products based on the USS-720 connecting to the same USB bus, it may not be clear which device is connected to which USBLPTx port.

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 data in the EEPROM provides a means for the developer to ensure that only their software is loaded for use with their device.

USBLPTx Ports

Evaluation kit version of software: For each USB Smart Cable plugged into a host’sUSB,
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 associ­ated with the port. If no printer is associated with a USBLPT port when the corresponding USB Smart Cable is removed, the port is removedfrom the system.
Modified version of the USS-720 software: For each USB Smart Cable plugged into a host’sUSB,
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 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.
