Exclamation [Q] Problem while in USB

Hi I have got LG Optimus 2X (how surprising) with Cyanogen latest nightly build.
When i put my Optimus in USB which is conected into the PC it just make random touches all over the screen including the home button.
I tried reinstal drivers for the LG, turn off debuging mode, diferent USB cable. Nothing helped

Does anyone else having this issue ?
