ELO touchscreen and Debian 7



Hello,
I have been pretty much desperately trying to get a serial B&R 900 series touchscreen to work on Debian 7 using the elographics driver.
The device works but it is not well calibrated, and we are using LXDE so the manufacturer tool does not work.

I have tried a mishmash of solutions, and currently arrived to this:
- No xorg.conf
- /usr/share/X11/xorg.conf.d/5-elographics-touch.conf with the following

Section "InputDevice"
        Identifier   "Touchscreen"
        Driver      "elographics"
        Option      "screenno"        "0" 
        Option      "ButtonNumber"    "1"       
        Option      "ButtonThreshold" "17"
        Option      "Device"          "/dev/ttyS2"
        Option      "InputFashion"    "Touchpanel"
Option      "MinX"            "3571"
        Option      "MaxX"            "382"
        Option      "MinY"            "3378"
        Option       "MaxY"            "662" 
        Option      "Name"            "ELO Touchscreen"
        Option      "ReportingMode"   "Scaled"
        Option      "SendCoreEvents"  "on"
EndSection

xinput list returns a "Elo Touch Screen" device, but it seems to be unaffected by any of the above Options.
I think all I need to do is find a way to convince X to match the touch screen to the  InputDevice section (or use a correct InputClass) but so far it has escaped me.
The above works correctly on Debian 6 if it matters.

Thank you for your help!

Best regards,
Luca
