I have worked with the Elo drivers before.  These days (considering you have a newer Elo touch) you use the drivers in X.  You can find how to setup the drivers at:
 
http://www.elotouch.com/support/linux.asp
 
The newer versions of X (4.x.x) include some Elo drivers that should work.  That is what Elo suggests using.  Just look for the input driver as instructed and see if it works.  Otherwise, I would look up the particular model of Elo and try googling for it from there.
I'm glad you asked about Elo's instead of 3M touchscreens so I could keep my email message at a PG rating ;)

Subject: X with touchscreen monitors

Does anyone have elo graphics touch screens drivers and touch screen calibration utility for 2.6 kernels.  In particular CentOS 4.3, the comparable to RHEL 4, updates 3.

 

I can make the touch screen work with the elographics X drivers but the right way is to use the package from elo which I have been unable to get from them.   It’s a kernel level driver and calibration tool.   The package would likely be called elotouch-1.1somthiing.rpm based on the little that I know.
