Oh, please also send the output of: $ ls -l /sys/class/hwmon/hwmon*/device and $ ls -l /sys/class/hwmon/hwmon[45]/device/ And I am curious about your USB device and what sensors it has. If these are I2C sensor chips and there's an I2C bus inside the device, it may make more sense to write a bus drivers for that I2C segment, and use regular I2C sensor chip drivers on top of it. But of course it depends whether you have all the needed technical information to do this or not (if the hardware design allows it at all.) -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
