I've run »eeprom –w« and these last bytes did not change. may be give ftdi_read_chipid() a try :) The example program "simple" prints it for R type devices. The ftdi_read_chipid() function does quite some bit shifting to "unscramble" the id. Cheers, Thomas -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
