One wouldn't lend money to people they don't know, because they don't trust them. It's the same with our smartphones and tablets.

Lack of attention is all it takes to damage a USB port, especially the 4 pins. If one of them is damaged, the USB port becomes useless, and will not be able to recognize devices that are plugged in. If you plug in your iOS device, the unknown error occurred (0xE8000015) popup can show up. Maybe the USB port your device is currently plugged in is broken.
Luckily, there are more than one USB port on computers. Unplug the lightning cable from the USB port it was currently plugged in, and plug it in another port. Your device and the computer should react with a sound and iTunes should turn on, once a successful connection is established.
The lightning cable's purpose is just to connect your computer and the mobile device. It only serves as a relay through which information is exchanged. In order for the connection to be established properly, all the "parties" have to be connected to the USB cable, as if at least one isn't, then connection won't be established. The connection is initiated from your device's lightning port, and your computer's USB port, especially their pins, which can often get dirty, preventing the USB cable to get to them.
Maybe the device's lightning port, or computer's USB port is dirty (e.g. clogged with dust lumps) and prevents a successful connection. To clean the ports, pour some rubbing alcohol on a piece of cloth or an ear bud and clean the ports, gently, to avoid damaging them. Try connecting the devices again after 5 minutes.
