Must not be a firmware update needed. I bought both devices within a week of each other, same brand, name and number. Both stay plugged in all the time. I just connected the one I had plugged in but not in use. Tried the other one. Connects and plays fine and stays connected. I ordered another one and tomorrow I'll call the man who is the manufacturer. He was very helpful when I was leaning how to use them. Terry My latest photos at Http://www.flickr.com/terrypogue
