I made it work. Had one grey cable instead of green, one white with black stripe instead of white. The black cable is ground, which I connected to both the black cable of the USB cable and the power supply. I also connected the shielding cables in the extra foiled parts and wrapped these foils with aluminium foil. At the end i wrapped everything with aluminium foil. The brown cable comes to the red cable of the 12 V 2 A power supply.
