This Link was helpful for me:

As fred mentioned:

- load module via:  modprobe elo
- run inputtattch: inputattach -elo /dev/ttyS0 --daemon

You could add a rule for udev,
e.g. /etc/udev/rules.d/99-elographics.rules

This is my rules file:
#################### Start file 99-elographics.rules ##################
ACTION=="add|change", SUBSYSTEM=="tty|pnp", KERNEL=="ttyS0", RUN
+="/sbin/modprobe elo", \
RUN+="/lib/udev/inputattach -elo /dev/%k --daemon", \
ENV{ID_INPUT}="1", ENV{ID_INPUT_TOUCHSCREEN}="1"
#######################################################################

But be aware, that you shouldn't start the host without the touchscreen
attached to the serial port. I did that and my logs was bloating up to
5GB, because of inputattach error messages.

Maybe this link is helpful as well:
