I am brand new to this forum. I have what I believe to be a second generation 8gb iPod Nano. Two days ago I connected my iPod to my mac via the cable which was supplied with my iPod when I purchased it, and nothing happened. I have tried plugging it in in different places on my mac, such as my keyboard with no success. The iPod will charge, but that is it. Any ideas what my problem might be? Thanks.
