If I understand it correctly all you want is to create the _userspace_ program that will send commands to the specific device on the bus. If so please have a look to linux-2.6.x/Documentation/i2c/dev-interface Further example could be found in lm-sensors package. i2cdump.c i2cset.c etc... I hope this helps, Regards Rudolf
