The notebook is equipped with a touchpad manufactured by Elan microelectornics Corporation. The board number is 2H214-14201 Rev B. The controller IC is Elan 339360-3100. I have found no information about them on the web. I might run a round with Elan in e-mail, but I do not really have big hopes about it.

I do not have schematic for the original mainboard but have one for an another similar Samsung Ultrabook with discrete graphics codenamed Miranda 13H-EXT.

The pinout of the touch connector is the following:

The KBC3_TCLK/TDATA goes to the superio/micom while the SMB3_CLK/DATA hooked to the PCH's SMBUS to the same one which connects the RAM slot's SPD eeproms. Unfortunately I have no luck powering up the board to boot (if I could not this conversion would be it's destination), so I could not run an I2C detect from Linux to see it is answering.

The KBC3_TCLK/TDATA interface I guess is a PS2. I will power up the board's P3.3V to see if it outputs the clock. PS2 differs from I2C so it would be tricky to interact with it. SMBUS would be better because it could (or should due the lack of free pins) share the same bus with the lipo battery gauge.
