More tips from Device not recognized in Windows

1. Update iTunes

2. Check the USB cable

3. Verify that Apple Mobile Device Support is installed

4. Restart the Apple Mobile Device Service

5. Verify that the Apple Mobile Device USB Driver is installed

6. Check for third-party software conflicts

I guess its the problem of Drivers. Try to install iPhone drivers.

Also install latest iTunes version so that the drivers will be updated.

(1) Have you tried a different USB Cable?

(2) Is your iTunes set up to Open when Your iPhone is Connected?

(3) Does your iPhone charge via the Apple Power Adaptor?

(4) Reboot iPhone - ReBoot Computer -

(5) Make sure your iPhone & iTunes are both running the latest Updates..

(6) Turn Your iPhone Off, then connect to the computer - see if it activates..

It's the driver problem with your drivers in your PC, nothing with the cable and nor with the iPhone.

Try few of the links and see if it works. or else reistall your OS on pc with latest version of windows atleast 7 for that matter. Don't Install XP.

Hi, I had the exact same problem as you and had the same phone, I tried every solution on the web but it still didn't work, so I took it to Apple and it wouldn't appear on there Mac either, so they replaced the phone.

I’m pretty sure everyone updated they’re phone to 7.1 and they’re iTunes to 11.1.5… and probably plugged their device in the USB port. Then hit “trust this computer”. And STILL couldn’t find it. OR, even uninstalled iTunes a zillion times and then tried a new cord.. I was just playing around with my computer and found the solution for Windows 8 users. And possibly Windows 7 users. For Mac users: try something similar..

1. Plug your device in and do the usual “Trust This Computer” ******** on your device..
2. Hit START on your computer..
3. Type in PC SETTINGS..
4. Click PC AND DEVICES..
5. Click DEVICES..
6. Under OTHER DEVICES, click “Apple IPhone/IPad/IPod”..
7. Click REMOVE DEVICE..
8. Take the USB out.. Then plug it back in..
9. WALLAH..

Just clean the Iphone charger Port...

clean the iphone charger inserting gap..

man simple as this. all you have to do is to click the icon that says that USB is not recognized.

then uninstall the driver. remove device. then connect it again. the driver will automatically install.. I hope this helps.
