X51V: Can't calibrate on first boot

Hi all!

I've followed the manual exactly, but when I try to calibrate my
screen (as prompted on first boot), I can't do it, because calibration
becames an infinite loop (after I press the crosshair in the center of
the screen, it moves back to it start position - top-left), so I can't
go further. And by the way, to get crosshair moving to any next
position, I should press (anywhere on the screen) five or six times.

Thanks a lot and sorry for my English.
