The driver checks that all of these are in fact zero before 99 declaring the chip to be a MAX6 550/1.99 declaring the chip to be a MAX6650/1. 100 100 101 101 sensors-detect … … 103 103 104 104 Support for MAX6650/1 has been added to sensors-detect.

Like the 106 106 driver, it cannot yet distinguish a MAX6650 and MAX6651. 107 107
