Argh,
I didn't realize that ftdi_eeprom is now a part of libftdi-1.
Please test appended patch together with the one you find offending as above.
When ftdi_open happened before we tamper with the eeprom values, we have a
valid stub in the eeprom structure, no need set the chip type etc.
Perhaps this fixes your case.
B.T.w. ftdi_eeprom deosn't allow to reprogram VID/PID yet. The conf file
must supply VID/PID of the device to open and VIP/PID that should get
programmed into the device.
