I2C HID touchpad - can't get it to work

Hello,
I've got a problem with my I2C HID touchpad.
It doesn't get recognised by the system and doesn't respond in any way.
I followed the whole voodooI2C guide -> https://voodooi2c.github.io/#index
But still no luck, can anybody help me?

The keyboard which is connected via PS2 works just fine.
My laptop: Fujitsu Lifebook U939

I tried to somehow edit the DSDT file but nothing helped.
Original ACPI files attached.

The VoodooI2C.kext and VoodooI2CHID.kext ale installed in /L/E/...
