iTunes could not connect to this iPhone

One possibility is because of the device being locked with your passcode. Unlock the device by entering in your passcode, then try. Worked for my iPad.

I find it utterly incomprehensible that so many users are having such a difficult time with a core function like connecting their device to iTunes, let alone using it to sync, manage playlists, etc.

I have never been able to get iTunes to sync contacts, calendars, music, etc. without currupting iPhone's data.

I recently bought a Samsung ATIV Ultrabook / Win 8.1 and now I can't even connect my iPhone via iTunes.

FYI - I bought Xilisoft's iPad Sync tool - it corrupts my playlists, but at least I can now connect my iPhone to my new laptop and manually transfer files. Which I can't do with iTunes.

iTunes was orginally designed to play media. If Apple can get it to act like a store, that's jut great.

Apple - you are sitting on a cash hoard of $100B - has it ever occurred to you to spend a few bucks and reward your loyal users with a stable sync utility, istead of this total POS that wastes everyone's time?

Apple - for the rest of us. What an ironic slogan. The rest of us can't use your stupid software.

I had this problem with both my iPad2 and my iPhone 5 after the latest iTunes upgrade (to 11.4.0.18). I reinstalled to no avail.Then I found that it worked if first I entered my passcode to get past the lock screen on the device. Then when I connected the device, I saw the prompts to set up the trust relationship on both the device and the computer running iTunes. And all appeared to be well.

You on Kaspersky anti virus? I am. That was my prob. Could be yours. There's what you do. Open Kaspersky. Click on Settings/Additional/Network/Monitored Ports. Unclick [sorry, probably wrong expression] 'Monitor all network ports' and click 'Monitor selected ports only.'. Click Apply. Close Kaspersky. Sync. Go back to Kaspersky and do reverse of above. There's a massive handbags at dawn virtual personality clash over this between apple and Kaspersky. No one knows why. Hope it helps.

Go to Device Manager under Universal Serial Bus Controllers find " Apple Mobile Device Driver" right click on it uninstall and check "delete" also. Then try to connect the usb (iphone) to PC.

I have the same issue, just with a mac. Please help!

Me too.

I find it annoying that I cannot use my iPhone with my laptop to transfer some files. And they are both up to date is ios!
