I have been watching mp4 videos on a thumb drive plugged into the USB port of my Sharp TV with Roku. Recently the Roku Media Player stopped listing the USB device when trying to find a video to play. I have media player set to start when a USB is plugged in. But when I plug in the thumb drive, media player comes up but does not list the USB device for file selection. Any idea how to get the TV to list the USB device again?
Have you tried completely powering the TV off (unplug it) for about a minute, then turning it back on? I've had to do that with computers before. With my Sharp, I've only used the USB port once to test a media file, so can't say if it's an issue.
