after removing the USB cable of the touch screen the /dev/hidrawX show ........../dev/hidraw0  and /dev/hidraw1 

/dev/hidraw0         /dev/hidraw1

if usb cable of the touchscreen driver is connected then

/dev/hidraw0        /dev/hidraw1      /dev/hidraw2

we tried Linux kernel 2.6.36 and 3.0.8 but the touch does not work. (usbtouchscreen.c file given by you  as well as ilitek_lumv_3_8_6.c file ...)

Kernel 2.6.31 have no ability support any Capacitive touch screen
Because this arch OS only single touch as Mouse
But Capacitive touch screen work solution not as Mouse, it's response point report solution

we tried to uograde the kernel from 2.6.31 to 3.0.8  and we compiled the ilitek touch screen driver

we were able to get the touch to sence but it is not proper

and the calibration tool xcalibrator of linux does not work properly

now we are trying to see whether we can get 64bit older arch linux to install and see the touch and our software works or no
