Try using different usb ports on your computer. If it doesn't work then try hooking up your iphone to another computer. If it still isn't being recognized then try a different IPHONE USB cable.
If your Iphone still can't be recognized after all of this then read the article at the link below.

Also try restoring your iphone to factory defaults if necessary. This is a last resort. If your iphone still won't get recognized by the computer then it could be the connection on the Iphone is defective and in that case replacing the phone is the only option.

My apple ihone is disabled connectto itunes

There are many reasons why iTunes will not recognize your iPhone, whether it's dust or dirt blocking your dock connector or a system setting gone wrong. No matter what model iPhone you have, here are a few suggestions for helping the problem of iTunes not recognizing iPhone:

1. Generally speaking, when iTunes does not recognize iPhone, it may have something to do with the version of iTunes. If you are using an old version of iTunes on your computer, it may not be capable of recognizing your iOS devices. So updating iTunes to the latest version is a fastest way to get the problem solved.

2. If you are running iTunes in the latest version, but still can't get your iPhone recognized, you may want to take a look at your computer, sometimes if your computer lacks necessary software, it might lead to the malfunction of iTunes.

3. USB port on your computer can be another reason why iPhone not recognized by iTunes. So you can try more than one USB port to see whether the USB port works well.

4. Of course, your iPhone may also be the cause of iTunes not recognizing iPhone. At this moment, you can restart your iPhone by holding the Sleep/Wake button and Home button at the same time until you see the Apple logo, then connect iPhone to computer with USB cable again.

5. You should also make sure your iPhone trusts your computer, because after changing a new system on computer, your iPhone will regard it as a new computer. What's more, you should check out whether Apple Mobile Device Support is installed on computer.

6. After checking out all the aspects mentioned above, you can try to connect iPhone to computer with the USB cable again.

If none of these methods work out, you may want to try set your iPhone up as new after iTunes not recognizing iPhone. You only need to tap General > Settings > Reset > Erase All Content and Settings, and then choose Set Up as New. When you have set iPhone up as a new device, you are able to connect iPhone to computer with USB cable. But before erasing all contents on your iPhone, you may want to back up iPhone files to computer to keep them safe.

How do you delete all your data when you forgot your password

  • Attach the phone to the pc
  • Turn the phone off
  • Hold power and home together for *exactly* 10 seconds
  • Release power but keep holding home until the pc beeps as a USB device is recognized.
  • At no point will the display come on. Now your restore should work.

My apple iphone USB Device Not Recognize what will

Go to www.itunes.com and download and install itunes, then reconnect the phone. If you already have itunes do this, but realize this will clear the info from your iphone, but if you have the info in itunes, it will sync back anyway. So just know, this does a factory reset:

Turn iphone off by holding power button on top left and sliding the red bar to shutdown.

Now, take the usb cable and have it not connected to the computer, but connect it to your iphone, so now you have the usb cable just connected to the iphone which is completely off.

Now, hold down the circle button on the iphone, and keep it held down. Then insert the usb cable into the computer, while still holding the button down. After a minute or two, you will get a screen on the iphone with a white usb wire pictured on the screen, and if you did it right, the connection should then pop up on windows. After you do the restore, you can then use itunes and plug in the usb like normal, all should be fine.

good luck!
