What am I missing here? There doesn't appear to be a way to access a USB drive that's plugged into the TV. A menu will pop up if I plug in a drive and it'll allow me to go through the menu. But if the USB is already in there, and I've moved on to another input, there doesn't seem to be a way to get back to the USB drive.

So again...what am I missing here?

ANSWER

1. Go to your home page. 
2. Where you see apps at the top, go to the + and add Video (Red folder named "Video"). 
3. Once added, press it and it will ask for permission to access the USB. 
4. Give it a minute to load your files, and you are done. Now you can access any USB content from the Video folder on your home page.
