I've done this so far:

sudo nano /etc/udev/rules.d/99-touchscreen.rules

And added:

SUBSYSTEM=="usb", ATTRS{idVendor}=="0408", ATTRS{idProduct}=="3000", SYMLINK+="usb/quanta_touch"
SUBSYSTEM=="input", KERNEL=="event*", ATTRS{idVendor}=="0408", ATTRS{idProduct}=="3000", SYMLINK+="input/quanta_touch"

sudo service udev restart

then the instructions here: http://ubuntuforums.org/showpost.php?p=8932808&postcount=36

And then added to my xorg conf:

Section "InputDevice"
 Identifier      "Acer T230H"
 Driver          "hidtouch"
 Option          "SendCoreEvents"        "true"

 Option          "CornerScreenHeight"    "1080"  # 1080 for 23"
EndSection

Section "ServerLayout"
    Identifier "Touchscreen"
    InputDevice "Acer T230H" "SendCoreEvents"
EndSection

And restarted. And the touchscreen does nothing. Any ideas?
