A:Answer Yes! I found a pdf of the User Guide online and it said this:
"Playing content from USB storage devices
Only in connected mode, your Home screen has the Roku Media Player tile. Otherwise, the Home screen has the USB Media Player tile. You can play personal music, video, and photo files from a personal USB flash drive or hard disk connected to the TV’s USB port.
To use this feature, make sure your media files are compatible with the Roku/USB Media Player. To see the latest list of supported formats, view Help in the Media Player*. The Roku/USB Media Player displays supported file types only, and hides file types it knows it cannot play."
