i read the webpages you suggested, thanks. still, tell me, is it possible that this all fails as in my distro slackware v13.0 32bit there is no elo X-module installed? see here :
find /usr/X11R6/lib/modules/ -name "*elo*"
this points back at the text in the webpage you suggested: "At first verify that the device driver modules exist. They are located in /usr/X11R6/lib/modules/". which is not the case for us using slackware v13. others had similar problems (in italian), see here:
i included "/sbin/modprobe elo" in the rc.local file (no error messages).
i used many entries for "device" not just this one:
Option "Device" "/dev/input/elo"
here some tests:
lsusb (with the ELO line)
Bus 003 Device 006: ID 04e7:0073 Elo TouchSystems
lsmod | grep elo
elo 4540 0
dmesg | grep Elo (while 'ELO' and 'elo' don't lead anywhere)
usb 3-1: Product: Elo TouchSystems Inc. APR Controller
usb 3-1: Manufacturer: Elo TouchSystems
elographics is good for serial ports, but not for USB ports. our newest ELO touchscreens are exclusively USB capable (while we also have six other serial ELOs running perfectly fine with the old driver elographics). we don't use currently serial-to-USB converters. moreover many motherboards don't come anymore with serial ports. in any case, we have no choice, we have to use this hew type of ELO for various reaosons.
i start to believe that for this kernel version and X-version there is no ELO-USB solution. what do you think ? sorry for getting back to you the n-th times. bye, pisti
