On a FT232R, FT_EE_Program() failed with error 18 if the string size was
> 46. So I think, there's a bug in AN_121, and using plain 96 on all chips
will lead to error. E.g. on a FT2232H, strings start at 0x1a(0x9a) and +
0x66 (0x60 bytes and 3 times length and string marker) will bring us to
0x7f(0xff), leaving no room for the checksum. And then the PNP marker
(0x02030000 or 0x02030100) is left out too.

The manufacturer ID is a tag used for the "automatic" generation of serial
numbers. I have never seen it in the real EEPROM, beside eventually as the
first letters of the generated
