Is/are your computer usb working? How do you know it is? Have you tried using different cables?
i am stumped as to what to do everyone...i curently am trying to hook up an mp3 player for my father and my brother HOWEVER... when i plugged them in for the first time and tried to install them the instalation could not complete for any of them (they are the sansa clip, the sansa c200, and the toshiba gigabeat) now everytime i try to pug them into the computer a series of low "dings" sound so the comp knows its in the USB slot. however when i go to "My Computer" and look for the removable device i see nothing , no extra drive no extra icon nothing. Oh all of them charge just fine its just the comp does not give me an option to drag music to it. PLEASE HELP ME!!!
