When you plug in any mp3 players on a WinXp OEM, usually it will recognise the hardware and all you need to do is to drag and drop music into the Mp3 player. But for me, when i plug my new K5 into it, it tells me that the USB device attacked to this computer has mulfunctioned. I tried plugging it into other computer and its all the same. Can anyone here help me diagnose this problem?? Your help is much appreciated! Thanks!!
