Hi,
first of all, i hope i'm at the right place to get my semi-geek problem
solved.
I just wanted to reconfigure the cbus pins of my UM232R (FT232RL). So i
tried to get this done with ftdi_eeprom.
But now, after i tried it for a while, the current eeprom looks like this
libftdi-1.0/examples# ./eeprom
Chip type 3 ftdi_eeprom_size: 128

Now i just want to bring the original eeprom back to the device with 0x14
replaced by 92. But the usage of ftdi_eeprom is a kind of obscure to me.
I hope there is somebody around to help me with this?
I thank you very much for your effort
with kind regards
Johannes
