Cannot connect to PC after using Nexus media importer

[Xenocidex]

Hey all,
I was playing with mounting a thumb drive using an otg cable and playing mkvs from it using mx player (succsefully btw), and now when I connect my Galaxy note 2 to any computer (tried multiple) the phone charges, but does not mount as a media device within windows.

Anyone have any ideas? I tried uninstalling the app, rebooting, pulling the battery, different cords and different computers.

I can still use the OTG cable to connect to a thumb drive and play files from it, so I do not believe I have damaged the hardware...
