    Hi my daily trouble is this: on two usb ports (on the right side, Aspire 5520) power randomly goes off. I usually have my mouse attached, and I see its led starts blinking, then it disconnects and switches off. The problem is in the ports, because when this happens other devices won't work in those two ports.
    After a long while, I try to attach something and they're back to life.
    Is it an hardware -- electrical? -- problem? Do I have just to call Acer tec support?

    Try going into device manager, and for all the USB hubs present, don't let Windows turn them off in Power Management.
