 +==== all in one USB cable ====
 +
 +To power and simultaneously connect an USB hub to the Raspberry Pi Zero with just a single USB cable one needs an [[https://en.wikipedia.org/wiki/USB_On-The-Go|USB-OTG]] cable.\\
 +
 +
 +An other possibility would be this [[raspberry:pi_zero_usb-otg|Pi Zero USB-OTG Hack]].\\
