Does not work since i2c-isa is an empty algorithm and has neither i2c_xfer or smbus_xfer. All low-level access is handled internally in chip drivers. I think there is isadump? The real benefit of i2c-isa was to use i2c-proc. With sysfs only i2c_detect (address parameter parser) in i2c-sensors.c is (sometimes) used. In addition, user progs may depend on data from /proc/bus/i2c* to find the chip. -- Ky?sti M?lkki <kyosti.malkki at welho.com>
