Restart

Turn off your computer and your iOS device, then turn them on again.

Update your computer

Check to make sure that you've installed all required updates for your computer.

Update iTunes

Make sure your iOS device trusts your computer

If you connect your iOS device to your computer and see "If you have not connected your iOS device to this computer before, unlock the device and tap Trust," make sure that your device trusts the computer.

If you use Windows XP and you see the trust alert on your device repeatedly, make sure that you installed iTunes. Learn how to resolve a repeating trust alert when using Windows XP. You might need to reset the lockdown folder.

Check the USB cable

Verify that the 30-pin to USB cable or Lightning Connector to USB cable is free of debris and not damaged. If another cable is available, test with that cable instead.

USB cables that are bundled with third-party products or accessories might work only to charge those products and might not transmit data. Also, if you're using a third-party case or extended battery pack, try removing the case and connecting the Apple-supplied USB cable directly to your device.

Verify that Apple Mobile Device Support is installed

iOS devices require Apple Mobile Device Support, which should be automatically installed with iTunes. To verify whether it is installed, follow the steps appropriate for your Windows operating system below.

Windows XP

  • Click Start.
  • Choose Control Panel.
  • Open the "Add or Remove Programs" control panel and verify that Apple Mobile Device Support is visible in the list of currently installed programs.

Windows 8

  • Move the cursor to the upper right corner and click the magnifying glass.
  • Type Control Panel, and press Return.
  • Click "Uninstall a program."
  • Verify that Apple Mobile Device Support is visible in the list of currently installed programs.

If Apple Mobile Device Support is not listed, remove iTunes, QuickTime, Apple Software Update, Apple Application Support, and then reinstall iTunes.

If the Apple Mobile Device USB Driver is not listed

  1. Disconnect the device from the computer.
  2. Save a screenshot by pressing the Home button and the Wake/Sleep button at the same time (the screen should flash briefly). Taking screenshots and saving images on iPod touch requires iOS version 2.0 or later.
  3. Reconnect the device to the computer.
  4. Open the Device Manager in Windows:
    • Windows 8:
      1. Move the cursor to the upper right corner.
      2. Click the magnifying glass.
      3. Type devmgmt.msc.
      4. Press Return.
    • Windows Vista or Windows 7:
      1. Click Start.
      2. In the dialog, type devmgmt.msc.
      3. Press Return.

    • Other Devices
    • Portable Devices
    • Universal Serial Bus Controllers
  6. Look for the entry that recognizes the device as a camera. This entry should be called Apple iPhone, Apple iPad, or Apple iPod.

If only "Unknown Device" appears:

  1. Right-click on the "Unknown Device" entry.
  2. Choose "Properties" from the shortcut menu.
  3. Click the Details tab.
  4. In the drop-down menu, select "Hardware IDs."
  5. If the hardware ID displayed starts with:
    USB\VID_0000&PID_0000
    This means that Windows cannot read the hardware IDs of the device, and so has replaced them with all zeros. This is typically caused by a faulty USB connection, or an incompatibility with your USB chipset drivers.
  6. Disconnect the device, and unplug all USB devices from your computer.
  7. Shut your computer down, then power it back on.
  8. Reconnect your device, testing each USB port for approximately 30 seconds to see if your device is recognized.
  9. Test with an alternate, known-good 30-pin to USB cable or Lightning Connector to USB cable if available.
  10. If you have an external USB 2.0 hub available, connect the hub to your PC, and then connect the iOS device to the hub.
  11. If your device shows up in iTunes, try disconnecting the external USB 2.0 hub and connecting the iOS device directly to your PC. If the issue returns, you may need to use the external USB 2.0 hub as a temporary workaround. Then, consult your computer manufacturer for any updates for your USB chipset.

If "Unknown Device" appears when connecting your device to more than 1 known-good computer, with more than 1 known-good USB cable, your device might need service. Learn more about your service options.

    Recovery Mode

If you see only one "Apple Mobile Device USB Driver" entry that has no errors on it:

Find out if the computer has USB 3.0 ports. Within Universal Serial Bus Controllers, locate any entries containing "USB 3.0" or "SuperSpeed USB" in the title. If these are listed, you have USB 3.0.

If you have USB 3.0:

  1. Try to connect the device to a different USB port. Try each port until the device is recognized. Some computers will have dedicated USB 2.0 and 3.0 ports. If so, a USB 2.0 port might resolve the issue.
  2. Refer to your computer manufacturer for updates to the USB 3.0 chipset drivers.
  3. If the issue persists, continue to "Check for third-party software conflicts."

If you do not have USB 3.0

If you see two "Apple Mobile Device (Recovery Mode)" entries with exclamation marks on them:

  1. Open the Device Manager and connect your device.
  2. Click the View menu.
  3. Select "Devices by connection."
  4. Locate the erroneous "Apple Mobile Device (Recovery Mode)" entries. You might need to expand all sections of the Device Manager to see them.
  5. Directly above these entries will be a USB Composite Device entry.

Check for third-party software conflicts

Certain phone and cellular device connectivity software from vendors such as Samsung, Nokia, Bora, Novatel, Sony, Android, LG, Sierra, Huawei, Pantech, or Motorola might cause your device not to be recognized. If you have such software on your computer:

  1. Uninstall the phone or cellular connectivity software temporarily, and test. Contact the manufacturer of this software for assistance in doing this. If you use the third-party phone or cellular device for your Internet connection, try connecting to an alternate network using Wi-Fi or Ethernet.
  2. Remove iTunes and all related Apple software.

    Remove and Reinstall iTunes and other software components from Windows XP
    Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8
     
  3. After reinstalling iTunes, test the device.
  4. If you still need your third-party phone or cellular connectivity software that was removed, reinstall this software and test your device to ensure it still functions with iTunes. Contact the vendor of your phone connectivity software if the issue returns.

Also, third-party security software might conflict with iOS devices connecting to iTunes. Follow this article to troubleshoot issues that might be caused by your security software. After resolving any issues that you might have with your security software, you might need to try the steps in this article again.
