(...after some research...) Best would probably be updating the Xorg evtouch-driver. It looks like someone already did this. I found a site containing a quite complete description of (hopefully the same) problem: http://zalman.ostergaard.net/touch.html However I don't think the changes were submitted upstream as the (new) driver does not contain support for the other eGalax-hardware anymore. In my view the problem is not the Linux usbtouchscreen/usbhid driver, but the evtouch-driver. It looks like the evtouch-driver is not maintained by the Xorg-folks, but on http://www.conan.de/touchscreen/evtouch.html (contact added in CC). Anyone interested in creating a patch for evtouch?
