One last idea before you give it away? Try a new USB cable.
I got a new mp3 player for xmas - it's not branded in any way shape or form. When I plug it into the computer it charges okay but it doesn't come up with the folder my songs are in. I have tried device manager but no luck. Our mouse works fine in the usb ports....but I've tried all 3 and none of them will work. Please help!
