To be more exact, see chapter seven in:

http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT232H.pdf

"If the FT232H is used without an external EEPROM the chip defaults to a
USB to asynchronous serial UART (RS232 mode) port device. If no EEPROM
is connected (or the EEPROM is blank), the FT232H uses its built in
default VID (0403), PID (6014) Product Description and Power Descriptor
Value. In this case, the device will not have a serial number as part of
the USB descriptor."

If we wanted to go to SPI, synch FIFO etc we would need an EEPROM.
