Hi there! I have a little prob with my speakers/mouse. When i move my logitech M215 wireless mouse my USB-powered Altec Lansing Speakers make a buzzing noise. WHY!?!?!?! The noise isnt loude, but its annoying when its quiet. It only goes away, when i connect the speakers to a seperate USB charger. Mute doesnt work either. Annyone who knows a fix? PLLLZ!!!
