[Expert-At-AnyThing]

when i plug it in, my computer says unknown device and itunes doesn't open up or anything. I tried reinstalling itunes and everything. So how do  i fix this problem. its a ipod shuffle and im using windows 7.

Has it ever worked properly on that computer before? Are you trying it in a rear usb port? Can you still access your itunes library without the device?truenorth

Have you gone through the process to synch it to the laptop. I use an older ipod shuffle and i remember having to synch it to the computer before i could have it recognized. Here are a couple of sites to give you guidance on that.
