So SCCB is really only another name for I2C or are there differences in the protocol? If the first holds, then the infrastructure is already thereand you should be able to use the i2c commands. If the latter then you really shoudl come up with your own "sccb" driver. Probably basing it on drivers.i2c/soft_i2c.c would be a good idea. > Here's my question: > If my sensor has power and a clock, does it response to the I2C probe or I > have to modify it too?.

If this is at all like I2C, then it should definitely answer when its clock and data pins are driven by I2C. Did you check with an oscilloscope that you really are talking to the chip?
