after programming the eeprom of an FT245RL with ftdi_eeprom v0.17

how can i make it working?
Please use ftdi_eeprom from git HEAD.
Eeprom support is incomplete in libftdi 0.x.
Huh - is the *chip type* stored in the eeprom?
Unfortunately this is true for the FT245R vs. FT232R;
the FT245R has bit 0 set in the first byte of the eeprom whereas the
bit is cleared in the FT232R (whether the same holds true for the FT245
vs. FT232 without 'R' I cannot tell).
Even ftdi_eeprom from git HEAD is unable to cope with this :-(
The attached quick hack turns the problem upside down; with the patch
applied, ftdi_eeprom handles the FT245R correctly at the cost of
turning an FT232R into an FT245R, so it may solve Kofi's problem
short-term but is certainly not suitable for inclusion. Caveat emptor.
Cheers
