[SOLVED] Samsung built in Touchpad (ETPS/2 Elantech) doesn't send any events to the event file

I was playing around with event files (/dev/input) and noticed that event4 (touchpad's event file) doesn't produce anything when I touch and move over the touchpad. I've did lsinput but it doesn't really contain any useful information (except that version number is 0??). Any ideas why it might be so? Maybe I should install some driver or something? Btw the touchpad works fine itself - I can move the mouse using it, etc but it doesn't send the signals...

lsinput:

Code:

...
/dev/input/event4
   bustype : BUS_I8042
   vendor  : 0x2
   product : 0xe
   version : 0
   name    : "ETPS/2 Elantech Touchpad"
   phys    : "isa0060/serio1/input0"
   bits ev : EV_SYN EV_KEY EV_ABS

Nvm I know now why it happened. The touchpad driver was using the file and capturing all the events, so I have to disable it in order to read events from that file
