evdev and Trust TB-5300 tablet: wrong axis labels

[Daniil Kolpakov]

(Sorry, the email was send from wrong address. Resending it.)

Hi,

I'm playing with Trust TB-5300 tablet, which gets identified as "UC-LOGIC 
Tablet WP5540U" by HAL and xorg loads evdev driver for it on plug.

I'm getting the following list of axes with xinput list --long:
Abs X, Abs Y, Abs Z, Abs Rotary X, Abs Pressure (5 axes). xinput test shows 
output like this:

motion a[0]=0 a[1]=0 a[2]=32045 a[3]=16538 a[4]=55
motion a[0]=0 a[1]=0 a[2]=32072 a[3]=16575 a[4]=54
motion a[0]=0 a[1]=0 a[2]=32114 a[3]=16596 a[4]=49

a[0] and a[1] is always 0, a[2] is X, a[3] is Y and a[4] is pressure.

The result is that X pointer goes to (0, 0) every time I move pen over the 
tablet. Looks like two non-existing axes to me (I guess if I could at least 
remap them I could have the pen move X cursor properly). Is there anything to 
configure on this subject?

Output of the "xinput list --long" for tablet device:
