Hi
just found the problem: the code should be like:
eeprom->use_serial = cfg_getbool(cfg, "use_serial") == 0 ? 0 : USE_SERIAL_NUM;
from ftdi.c
~~~~
if (ftdi->type > TYPE_AM) /* use_serial not used in AM devices */
{
if (eeprom->use_serial == USE_SERIAL_NUM )
output[0x0A] |= USE_SERIAL_NUM;
else
output[0x0A] &= ~USE_SERIAL_NUM;
}
~~~~
