Hi Wolfram, I think the I2C slave support is an excellent feature you added to Linux (thanks for that) but I somehow have some problems to get it working on -rc4. What are the magical commands to get a linux slave on e.g. bus 1? What I tried: modprobe i2c-dev modprobe i2c-slave-eeprom # echo i2c_slave_eeprom 0x20 > /sys/bus/i2c/devices/i2c-1/new_device [ 16.119] i2c i2c-1: new_device: Instantiated device i2c_slave_eeprom at 0x20 # find /sys -name '*eeprom*' /sys/bus/i2c/drivers/i2c-slave-eeprom /sys/module/i2c_slave_eeprom /sys/module/i2c_slave_eeprom/drivers/i2c:i2c-slave-eeprom # ls -lah /sys/bus/i2c/devices/1-0020/ insgesamt 0 drwxr-xr-x 3 root root 0 18.
