Q: I installed iTunes 11.1.5 and it's not "seeing" my iphone 5s that's running IOS 7.1.

Do you have a Mac or a PC?

Does the iPhone charge when hooked up to the computer?

Have you ever seen a prompt on your iPhone to "trust" the computer?

Hmm, that's odd! It should have happened at least once.

Have a look at this article. Go right to section 2 where it walks you through resetting dialogs.

Have you tried a couple of USB cables? And are you using the original cable that came with your phone?

The items in this article would be worth trying.

Edit: Just saw you got things sorted. Great news!
