My iPhone 6 isn't being recognized by itunes

I've tried reinstalling itunes, restarting my computer, my phone. I even wiped my phone on my macbook.

The computer is windows 8. Everything is up to date, windows and iTunes and the iPhone.

When i run the itunes diagnostic with my phone plugged in it says it can't find a device.

When i plugin my phone a popup comes up on the phone asking if i want to trust the computer and i always touch trust.

This has been occuring for about a month now.

here is what was returned by the diagnostic:
