My son recently got an ipod shuffle. How do you get the computer to recognize the second devise? My computer keeps trying to update my ipod's info. on his?
You need to give each iPod a unique name - if they're both called
iPod there will be a problem. Once they have separate names you should be able to independantly control what gets synced to each device.
Also, try changing the drive letter of one(or both) of your iPods. Keep them well apart because the iPod can be confused by any other storage devices assigned a similar drive letter even though they may not connected at the same time.
