Hi everyone,
I need some help. I have an USB ELO Touchscreen that I'm trying to get to work in linux (MDK 10.2 to be exact).
The problem is that the X driver for the screen simply registers all touches on the screen on one vertical line - so in effect it becomes a linear rather than a 2D sensor.
I've used SnoopyPro in Windows to capture some USB bus communications between the screen and Windows. Using that I was able to decipher what the data packets should look like and what they should contain. The problem is that when I then go back to linux and watch what is written to /dev/input/event2 (which is where my touchscreen events end up), the data doesn't match what I expect.
Is there some way that one can put the usbhid driver or perhaps the usbcore driver into a debug mode that will log all the communication packets in a text file (like /var/log/messages)? I'm well aware of the fact that it will be a rather big log file, but I have only the touchscreen connected to my USB bus at this time and really would like to understand what is going wrong so that I could either fix the driver or write my own.
Any ideas on how I could address the problem will be welcome.
Thanks in advance, Eduard
