iTunes: Compatible Personal MP3 Player Isn‘t Recognized

Your personal MP3 Player may not be recognized by iTunes if you install an earlier driver than the one that comes with iTunes.
Symptom

iTunes does not recognize a compatible MP3 player device, even though you've installed the USB drivers that came with the player.

Solution

Reinstall iTunes. The USB drivers that came with your player are too old. The iTunes installer will install later USB drivers that are compatible.
