What build of Windows are you running? Everything was alright in build 1607, I just had to restart a few times. I still had 2 unknown devices, those are the fingerprint scanner and the gyroscope. The other two that you don't have, I don't know what they are, but if you look at the BIOS name in device manager, that could be useful. That's how I found out what my devices are, for example the gyroscope had GYRO in its BIOS name.
