A Note on PIDs for TUSB3410UART EVM
Prior to March 2005, the EVM shipped without an EEPROM device in socket U5. As a result,
the TUSB3410 reported its default VID, PID, and serial number to the host, and the INF files for
the VCP driver were configured to associate with these values. TI provides another driver
(AppLoader) that associates with this same VID/PID pair and has found that many users have
run into conflicts due to having both drivers installed on the same host machine. In addition, TI
is planning to release a new utility in 2Q05 that also uses the default VID/PID.
In order to resolve these common conflicts, as well as enable the use of both the VCP software
and the new utility on the same machine, TI has changed the PID reported by the EVM to
“341A”. An EEPROM is now included on each TUSB3410UART EVM to implement this change.
