Hi all, I just bought a SamsungDigital Audio player(YP-T8Z)and tried to work on it with my PC,when I plugged the USB cable to my laptop,the PC would not do anything and the Display Screen on the Player would say"USB Disconnected,Safely Removed from PC".If any button pressed,nothing would respond.Do you guys have any idea what I should do to get this thing to work?Thanks.
