Virtually _all_ addresses are possible, as the I2C address can be changed just by writing the new address to a register. So we don't want to probe all possible addresses. > Something like scanall=1 or similar? Or maybe that option already exists? We already have the "probe" parameter, through which a user can ask the driver to probe additional arbitrary addresses. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
