I'm trying to use it from a Raspberry Pi, so I can't use the prebuilt drivers on that CD. I've found the ARM-specific vendor drivers but I haven't installed them yet as I remember this working without them on an older model of eGalax touchscreen. > > Even without those, it still seems to autodetect the touchscreen and it loads the hid_multitouch driver, and within X the pointer moves according to touches as expected. However it does not perform any "click" action when the screen is touched.

I've included some diagnostic output from various tools below in the hope that it may be useful to identify and/or fix the issue; please let me know if you need more information. No it's not a known issue.

The kernel does not sends the touch begin and touch end information, thus the device is not working :( Can you compile and install hid-recorder from http://bentiss.github.io/hid-replay-docs/ ? I would need a hid-record of your touchscreen so I can figure out why the kernel does not handle it properly.

The "Pen" device does not seem to be generating any events on touch (but then I don't have a magic touch pen, just a finger or passive stylus; I'm not sure if that makes a difference). > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-input" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
