I've try to add this function:

$(function(){
 $('.dc-mega').hover(function(){$('html').css('background-color','#676767') } );
});

But didnt work out .. .

here is the full jquery code of my megamenu (Js file) .. if it may help .. . Would really appreciate it, thank you so much !:

Solution

Write a udev rule that sets the permissions on the device node appropriately.
