We picked up a third mini yesterday, for our son. When trying to set up an iTunes account for him, the computer never would find the device. Eventually, it occurred to us to try one of the cords from our other minis, which worked instantly. We'll attempt to exchange the cord only at Walmart today, though they will likely insist on exchanging the whole package. Hope not, since we spent a good deal of time getting it set up for him. Anyone else seen or heard of this problem? Are we overlooking anything?
