I doubt that you can get any kind of reasonable speed using the CBUS pins on a FT232R. Accessing the CBUS pins is totally unbuffered. You can send one bit per URB and read one bit per URB. That will result in flash times not measured in minutes, but hours... What I have successfully done though, is using the CBUS pins in combination with a bootloader integrated into the controller by the manufacturer. You use the CBUS pins to enable the bootloader and issue a reset. Then you use the regular serial interface of the FT232R for speaking to the bootloader. But this has nothing to do with OpenOCD.
