Hi all Please can you modprobe the bus driver modprobe i2c-i801 modprobe i2c-dev i2cdetect 0 And send us output of i2cdetect command? Somewhere in region 0x20 - 0x2f should be one number. Use it in next command i2cdump 0 0x2f 0x2f is an example. Most likely it will be 0x2f or 0x2d or 0x2e Are you sure you ran /usr/local/sbin/sensors-detect and not /usr/sbin/sensors-detect Thanks, regards Rudolf.
