    I'm using Dell n7110, Win 7

    Recently I bought usb fan (small one, not the pad) and it worked good for few days, then I started to get this message:

    Power Surge in hub
    A USB device has exceeded the power limits of it's hub port. For assistance in solving this problem, click this message.

    I've read lots of posts about this but can't find the solution.
    I have 3 usb ports, now only one of them works. I can't have 2 usb cables or anything plugged in at once.

    Help :(

    The error usually means a USB device is drawing too much power. It may or may not have already caused USB power damage. If the issue only arises when using a particular device, then that device is likely the cause and/or faulty. If it now occurs with all devices, I'd suspect the USB controller is damaged/faulty.
