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.
