Hallo,
i have a eGalax PCAP touch controller. If i connect it to the system I
get a /dev/input/event0 and /dev/usb/hiddev0.
The /dev/input/event0 device return an emulated right click event if I
hold my finger on the touchscreen. On the /dev/usb/hiddev0 I can't see
this behaviour.
I want to disable the right click feature and have a look at the usbhid
driver, but this is quite complex so I can't find where this function
is.
Thanks all
Thomas
