Appendix A – FT2232H EEPROM Configuration
The RPi HUB Module utilizes an EEPROM which contains the USB configuration descriptors for the
FT2232H. When the RPi HUB Module is plugged into a PC or a USB reset is performed, the PC will read
these descriptors. The default values stored into the EEPROM are defined in Table 7.1.

Table 7.1 – Default Internal EEPROM Configuration
The EEPROM for FT2232H chip on the RPi HUB Module can be re-programmed over USB using the utility
program FT_Prog. FT_Prog can be downloaded from http://www.ftdichip.com/Support/Utilities.htm. Users
who do not have their own USB Vendor ID but who would like to use a unique Product ID in their design
can apply to FTDI for a free block of unique PIDs. Contact FTDI support for this service.
