I can read that, but I can also change it using the »ftdi-eeprom« program.
However, the ft245 datasheet mentions a factory programmed, non-alterable chip ID, which can be used to identify each particular device. This is described in the AN232R-02 application note from FTDI. I can see some »random« values in the last eight bytes of eeprom, cuold that be it? I've run »eeprom –w« and these last bytes did not change. Marko Cebokli From: E.S.

Using the "ëeprom" example program, I can see some random looking bytes at the end of eeprom, is this it? I guess it is not the "serial number", because that can be changed?
