    Default USB hub keeps disconnecting in windows 8

    hi, guys

    coming here for some help because you guys have fixed all my problems in the past.
    two weeks ago i purchased a Targus 2.0 4 Port USB hub which is powered by the computer and it has never really worked right. and my pc is running windows 8 64 bit.
    I usually have plugged in a wireless mouse, a usb keyboard, and my iPhone cable...that's the reason why i bought the hub. now sometimes it will work fine for a while but then all of a sudden it will start disconnecting and reconnecting and I have to stop using it for a while.
    I was very upset of this phonomenon so i am waiting here for some computer taents' help.
    any help would be greatly appreciated.

    Just follow what Sophip said. It is useful to fix the problem of USB keeps disconnecting in Windows 8. But first, you should check whether the port is loose.

    Im having a similar problem. My iPhone 4S isnt recognized at all in windows 8 64 bit ... i therefore cannot sync it with iTunes ... thats quite annoying. ANother USB problem i think, is when i try to RUN Call of Duty 4 - when the game loads i get the sound from when you disconnect an usb device, and then the one from when you CONNECT one... this repeats quickly 3 times and then the game freezes.... wh would a game cause this? ... until i press ctrl alt delete , the mouse isnt working :S

    I am having a similar problem with USB devices connecting and disconnecting multiple times while playing a full screen game. Most notably if and when my screen saver kicks in. Running a 3 monitor SLI setup. not sure if that helps. thought it was heat at first, asus rampage 3 with a 990x i7 cpu, not overclocked

    Thank you so much for the info. Though I did find the Renesas name in my Device Manager, no option was available to enable or disable power management. So I am at a loss at this point.

    Do you have a USB hub connected to this USB port? If yes, one probable reason is having too much peripherals on 1 USB port and the port cannot cope up with supplying enough power and data transfer speed demand. That is one casue or random disconnection. You should try to distribute the load to the other USB ports. Or use a self-powered hub (with AC adaptor).

    If No, esp if you said it is more notable when the screensaver kicks in, it is somewhere in your power management settings. When the screen saver kicks in, that means your PC is idle and your current configuration is shutting down these USB ports to save on power. See sample pic below:
