etokki iNPiN PS2 to PS3 Converter

Hey guys,

i bought the etokki inpin ps2 to ps3 converter awhile ago

when i tried it out on an FPS, the crosshair would move on its own after playing for about a minute,


I tried two dualshock 2s, the black and the silver one.

Does anyone know why it does this, and if it works normally on the other colored controllers ?

Thanks
