I bought a 2013 Fusion at the end of February. I set up a flash drive with a much of music, spent a few frustrating days getting it to work right (once I found out about meta-data tags and how to set them). I would leave the flash drive in the USB port most of the time, taking it out only when I had new songs I wanted to put on it. For the last 5 months, it's worked great (barring occasional problems with voice commands). Last week, for some reason, it stopped recognizing the flash drive. If I used the voice command, "USB", it would say "No USB device connected" and send me to Line In. If I used the menu and selected USB, it would show "Initializing" for a few seconds and then show, "Device not supported." I plugged the flash drive into a computer and was able to access it, play music from it, etc. I moved everything to another flash drive and it works, but the original one still doesn't. Does anyone what can cause this to happen? Could leaving the drive in the USB port do it?
