Notes for Developers (continued)

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. Otherwise, the enumeration of a camera using the USS-720 could cause the software for a USS-720- based printer to be loaded, resulting in a system which does not function correctly.
