Q: Trouble syncing iPhone 4s

I have been syncinc my iPhone 4s to my laptop for the past few years now. Within the past month or so, it hasn't been working. When I plug my phone into the USB port, a message pops up on my phone asking if I want to "trust" or "don't trust" the computer. I click trust and it waits about 5 seconds, then makes the disconnecting sound from iTunes. Can anyone help me out?

iPhone 4S, iOS 7.1, iTunes 11.1.5

    Hello D_Stradling,

     

    It sounds like your phone is disconnecting from your computer shortly after selecting to Trust the computer on the phone. I recommend troubleshooting the USB connection between the computer and the iPhone with these steps from the article named:

    Try the following steps to check the connection between your device or computer. You might need to do only one of these steps to resolve the issue, so test your connection after each step.

    1. See if the cable connection at the device or computer has come loose or unplugged.
      Unplug the cable you're using to connect your iOS device from the USB port on your computer, and then reconnect it. Then unplug it from your iOS device, and reconnect it.
    2. Remove any third-party battery packs or cases from the device and ensure that the USB cable is connected directly to the port on the device.
    3. If your Lightning or 30-pin cable is connected to a keyboard, display or USB hub, try plugging it directly into a USB port on the computer instead.
    4. Close any virtualization apps (such as Parallels or VMWare).
      These apps may interfere with your computer's ability to communicate over USB if they aren't properly configured, or up to date. If this resolves the issue, contact the developer of the app to see if an update is available.
    5. Restart your computer.
    6. Restart your iPad, iPhone, or iPod touch.
    7. If you're using an accessory or third-party cable to connect your device, try using an Apple cable with the device instead.
    8. Update to the latest version of iTunes if you have not already.
    9. Disconnect other USB devices from your computer, except for your keyboard and mouse. Then, reconnect your iOS device. If the issue is resolved, reconnect the other USB devices one at a time. Make sure your iOS device is still recognized by the computer after adding back each device.

    If one of these steps resolves the issue, but it comes back later, make sure you haven't changed how the device is connected. For example, check to see if you plugged the device into a specific accessory, or used a specific cable that reintroduced the issue.
