How would I go about upgrading that IOS to the latest (7.1.2)?
Have you tried it on a different computer? My guess is that the drivers in your windows machine( or is it mac) are corrupted. I too had an issue of usb not recognising the phone and after formatting the computer, it worked.
Since your charging works, the problem seems to be with your computer.
