One of the most common problems we encounter when connecting iPhone to a PC is that it does not recognize, it does not detect. To solve this we just have to follow these simple steps and the problem, almost certainly, will disappear . We have to go to Start -> Control Panel -> Device Management, Here we have to look for the iPhone in the "other devices". We click with the right mouse button and give "update driver". We will then ask where you can find the driver, select "Automatically search for driver". We finish the process by following the instructions appear on the screen and ... ready ... and should recognize the iPhone. In the event that have not yet detected, try rebooting both teams, both the iPhone and the PC and try again . I hope you have been helpful.
