As I can reproduce this problem on a standard tty device without X (see below) I am suspecting a driver problem, but I might as well be wrong. > > I assume you are talking about v3.6.7...

On modprobe the Kernel log says [12537.335946] input: eGalax Inc. USB TouchController as /devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/input /input13 [12537.336875] hid-multitouch 0003:0EEF:725E.0001: input,hiddev0,hidraw0: USB HID v2.10 Pointer [eGalax Inc. USB TouchController] on usb-0000:00:1d.2-1/input0 but /dev/input/event13 is not created. To be honest, I don't even know, if it should be created. What happens is, that /dev/input/event10 vanishes on removal of the hid-multitouch module and then reappears after modprobe. But a cat on it wont show a reaction while touching the screen's surface. > > I have this problem since moving to hid-multitouch for handling this device. > > What kind of driver did you use before? I think, there was a separate usb touchscreen driver for egalax devices before something like kernel version 3.2. This one I used. Long story short: I have never used the vendor supplied drivers, but those coming with the kernel. Cheers, Jan > > I will be happy to test and supply more information.
