I hopefully will get back soon a batch of 26 boards with FT2232H and blank
93x66 on it. So no easy way to tweak in that case.
But the other usage pattern the new code allows is:
* open device
* tweak values
* ftdi_erase_eeprom() (NOP) on FT232R
Even so my first mail was long, I shoudl have made it longer...
