I have a 3rd Gen iPad which is sync-ed with iTunes running on my Windows 8.1 PC. I sync only when I need to load new stuff. I wanted to transfer some books and connected my iPad and it was not being recognized. I updated my iTunes to 12 but still not connecting. Device manager says that driver is missing. I have uninstalled iTunes and reinstalled it but to no avail. Now windows update is not working too. Help.
