Calibration problem with Genius 4x5 tablet

Hello,

I have a Genius 4x5 tablet (Tablet WP5540U)
I was following the how-to at:
https://help.ubuntu.com/community/TabletSetupWizardpen

The problem is that the pointer is alway in the top-left corner.
I tried experimentig with the values but with no luck.

Has anybody an Idea where can be the problem?
In case you have the same or a similar tablet working can you paste me
your values?

Thanks :)

/wizardpen-calibrate /dev/Tablet
Please, press the stilus at ANY
corner of your desired working area: ok, got 741,32745

Please, press the stilus at OPPOSITE
corner of your desired working area: ok, got 32739,1289

According to your input you may put following
lines into your XF86Config file:

Driver "wizardpen"
Option "Device" "/dev/Tablet"
Option "TopX" "741"
Option "TopY" "1289"
Option "BottomX" "32739"
Option "BottomY" "32745"
Option "MaxX" "32739"
Option "MaxY" "32745"
