IPod touch
Before October 12, 2011, when the iPod touch is taken out of the box for the first time, it needs to be connected to a computer for it to start. When it's first turned on, iTunes must be installed on either a macOS or Microsoft Windows operating system computer for programming the iPod touch. On either operating system, the iPod touch needs a USB 2.0 port on the computer to connect. When the iPod is first turned on it needs data communications with iTunes, and will always show the "cable to iTunes" picture until it senses iTunes.
