I have an ELO touchscreen EL1725 connected via USB. The screen works without problems under gnome, but JavaFX does not recognize touch events.
If e.g. Calculator example app was started in gnome from a terminal window, all touch events are "ignored" from JavaFX and handled from gnome.

If I start the same application from a console, touch events are not handled.

My mouse works in all modes!

I built an Angstrom image 2012.05 based on the documentation - http://jdk7.java.net/fxarmpreview/javafx-arm-developer-preview.html - from scratch.

My problems are the same as described in RT-25872.
