Computer wont recognize mp3 player when plugged in. [Closed]

just brought an mp3 player, went to plug it into my computer (windows 10) and it simply just doesnt recognize its been plugged in. i have been on to my pc and it just doesnt list the device? i have messaged the seller thinking maybe it might be the mp3 itself but then again it may be the computer?
ps i have had no other problems with the usb cords when i use it for my iphone etc.
