Automatic STMP3500, Help Needed

[rascard2007]

a friend of mine came with a dead MP3 player, when I connected to the PC windows automatically identifies the player as STMP3500 Player Recovery Device, and mounted it as occult in the USB devices list. So I assumed that it´s a Sigmatel MP3 Player

Any attempt to work with it using MP3 player tools or MP3 Product Tools have failed because they didn´t find the device connected to the PC.

How can I solve this problem and recover the player?

thanks in advance,
