Find the parts of /var/log/Xorg.0.log after I plug in the USB cable of the Touchscreen in the attachment. It shows:
[ 80.799] (**) Option "InvertX" "1"
[ 80.799] (**) Option "InvertY" "1"
[ 80.799] (**) Option "SwapAxes" "1"

I can verify that these values were set by executing the following (10 is the id of my touchscreen):
xinput list-props 10
...
Evdev Axis Inversion (263): 1, 1
Evdev Axis Calibration (264): 30, 1902, 25, 1078
Evdev Axes Swap (265): 1
...

but as described above, no effect. evdev seems to ignore all of these options.
