Computer does not recognize OPPO S11 MP4 PLAYER
My computer does not recognize my mp4 player as an external drive, so I am unable to add or delete songs and photos. The player plays music and photos OK. However all that happens when I plug it into my computer via the usb cable, (mini usb male to standard usb male) is that it proceeds to charge the unit. Any help would be great! Many thanks in advance.
