Wierd (2 me) issues attempting install touchscreen

It seems Acer is using all kinds of obscure touch screen solutions.

Mine is an Acer B226HQL which lsusb shows as 0408:3021, nothing like yours dracozny.

Unfortunately I had no luck with hid-multitouch. The module looked like it loaded, but no working touch screen.

And isn't there a need to set up a rule to make it work? I know the rule I set up fails, at boot the first thing that comes up is:
[ 12.206599] generic-usb 0003:0408:3021.0002: usb_submit_urb(ctrl) failed: -1

This is on my Debian (latest ISO) installation.

I kind of understand what you say cncbasher when you say touch screens as such isn't LCNC specific. What makes it special is that most solutions when faced with solving touch screen problems are to replace your kernel.
And replacing your kernel isn't straight forward when using LCNC.....
Adding kernel drivers isn't straight forward for a Linux newbie either. In particular when you need to make sure you don't mess with the RT part of it.

To top that up LCNC is in fact one of the few software packages where a touch screen really is useful, not just a fancy gadget with no real use as it is for normal computer use.

This is why I think the use of touch screen and how to make it work is a valid discussion to have here. I completely understand you guys who don't think there is much point to it, and I will not argue with you and try to convince you to change your minds. But its evident there is some of us here who would like to have a touch screen on their CNC machine. The problem is that it seems to be quite a lottery if you get one of the good ones which just work or not.

Is there a list of good and bad touch screens for Linux? And in particular ones that works with the kernels used by LCNC? If not I would think it's a good idea to start making one on a wiki page. I might even start such a wiki page if I can figure out how to....

well I did not find a list of touchscreens I did however find a list of available drivers as well as a howto on a number of things wiki.ubuntu.com/Touchscreen

Anders,

Most Touch screens are quite generic in the way they work , it is possible to modify the install script and add your touchscreen model to it
then compile the hid-multitouch into the kernel , it's literally a one line entry copy paste and change a few numbers . to the ones you find
when probing the usb pid and vid

whats needed is the USB vid and pid information that comes up and name etc
i'll see if i can find my notes , i think i posted a while back some information on getting a touch screen working in 10.04
and that was an acer , so the same principle applys

unfortunately today is a bad day , i'll take a look over the next few days
if you find the vid and pid info email me , and i'll add it

I have updated the wiki with the info regards the Acer screen and the Ubuntu wiki

chipset for mine is based on ilitek, its a glitchy monster, I have had to play with various sensitivity settings to get it to behave(mostly). Oddly it will effect the standard mouse simultaneously when they are both plugged in.

I found a work around for my right click issue and that was the use of gestures using easystroke. it's not the best option but it gets it done

You may find you have to install more packages than what this guy lists in his last post in my case I also had to install
libxtst-dev
xserver-xorg-dev
The first part of this video she shows you how the gesture works for right clicking.


Hope this helps some of you.

Someone can help me?
I have an asus touch screen vt207 and the following version of debian and kernel
linuxcnc@debian:~$ uname -a
Linux debian 3.2.0-4-rt-686-pae #1 SMP PREEMPT RT Debian 3.2.73-2+deb7u2 i686 GNU/Linux

I tried to follow all the online guide to add the touch screen without success.
How can I add the ilitek driver in the right place?Is it possible?
