Solution
I have tried various sources on the net, but I haven’t found anything that would solve my issue, although the solution was fairly simple.
I have used the front USB ports on my Lenovo machine at work (haven’t tried it at home PC though) and when I’ve choosed to restore iPhone or iPad and after device restarted, Windows was looking for the iPhone/iPad drivers again. As this process takes some time because Windows always searched the Windows Update for drivers, device installation always failed.
The problem lies in front USB ports. I presume that low power or something else is the culprit.
So, before anything else, try to use onboard (rear side of your PC) USB ports. It should help.
