I just downloaded the latest itunes and so when I tried to sync my phone, and choose the "Trust" button my iphone immediately disconnects. I thought it could be the wire but when I tried charging it with the adapter, it worked. So I don't know what to do. Please help. I would really appreciate it.


iPhone 4S, iOS 7.0.4

    Hey there mvelez18,

     

    It sounds like you are not able to charge your device when connected to your computer because it unexpectedly disconnects after you tap Trust, but it seems to charge without issue when using the wall charger. I would use the USB troubleshooting from the following article to help resolve that issue, 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.

    All the best,
