USB MP3 player doesn't work

[opokharel]

I have a mp3 player of 128MB. It is not detected by any version of windows and linux now. Before, it worked well. It just displays the backlit and nothing else. Can anybody help me with this? Even the "new h/w found" doesn't come when I connect it to my PC.
