There are two G781 sensors connected to this bus, one to the > address 0x4C and one to the 0x4D. Both sensors have 0x01 as device id.

If they followed a naming logic similar to National Semiconductor, G781 will have address 0x4C and G781-1 will have address 0x4D. They are basically the exact same chip except for the address, so the driver doesn't even need to know, other than the fact that both addresses 0x4C and 0x4D are possible. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
