rm fteeprom/test/fteeprom-prog-bad When the magic command sequence for FT232R was added to libftdi-based fteeprom-prog, a version without this magic sequence was preserved in fteeprom-prog-bad. However, the new minilib version of fteeprom-prog operates without this magic sequence by default (as appropriate for FT2232D, FT2232H etc) and needs to be run with -r option to invoke FT232R-specific mode with the necessary magic. Anyone who needs fteeprom-prog-bad for study or experimentation can find it in freecalypso-hwlab Hg repository where it was originally developed.

 * Replicate these magic definitions.
