I have a TouchSystems capacitive touch screen that I'm using that works fine on an x86 Ubuntu system. On the UDOO it's detecting fine, dmesg: [ 249.668505] input: eGalax Inc. USB TouchController as /devices/platform/fsl-ehci.1/usb2/2-1/2-1.2/2-1.2.3/2-1.2.3:1.0/input/input4 [ 249.670451] generic-usb 0003:0EEF:72D0.0005: input,hidraw3: USB HID v2.10 Pointer [eGalax Inc. USB TouchController] on usb-fsl-ehci.1-1.2.3/input0 And running X, it shows up in xinput like it should. Initially it seemed to work, however, after doing a screen rotation and plugging in a new Transformation Matrix, it seemed to get unresponsive. - It responds to clicks, but doesn't move the cursor on the x/y axis). I've removed everything from the xorg.conf but I'm still having this issue. Has anyone experienced something like this before?
