Where do I find the HEAD of ftdi_eeprom?
I tried developer.intra2net..com and all I could find was sources of
libftdi, after compilation it gave me ftdi_eeprom ver. 0.13

So how to I find the right sources and finally be able to read and write
the EEPROM?

in HEAD (and 1.0) ftdi_eeprom is included in the libftdi package.

The download page is:
        http://www.intra2net.com/en/developer/libftdi/download.php

the source package of 1.0 is:
        http://www.intra2net.com/en/developer/libftdi/download/libftdi1-1.0.tar.bz2

and you can even follow the HEAD development in Git here:
        http://developer.intra2net.com/git/?p=libftdi;a=summary

This gives me version 0.17 of ftdi_eeprom while the Ubuntu system by default gives me version 0.3

I tried it anyway and it does not work as well. 

I am probably doing something wrong.
