Copnnecting iPhone 5S to Windows 8.1 Tablet (Possible Solution)
None of the suggestions worked to sync my iPhone 5S with IOS7.1 to my Asus Taichi Tablet running Windows 8.1.
Initially I could not connect my iPhone to iTunes using teh micro USB on the Tablet. Here's what I finally found that worked.
I installed iTunes and closed it.
I paired by iPhone to the Tablet using the Bluetooth. When I did this drivers were loaded.
I tried syncing but iTines did not see the iPhone.
I closed iTunes.
I then connected the iPhone to the Tablet using a USB to micro USB adaptor (non-OTG).
Some more drivers loaded.
I opened iTunes.
It found my iPhone and stepped me through the sync process.
My phone now has my music and playlists that are on iTunes.
Hopefully this helps some other people who are having the same or similar problems.
iPhone 5s, iOS 7.1
