 | The high-power 4 A power adapter makes this a tempting purchase, but some users report problems connecting devices with a USB 3.0 hub. Since Pi can't benefit from USB 3.0, better off to use one of the Plugable USB 2.0 7 or 4 port hubs like USB2-HUB-AG7 to both power the Pi and attached USB devices.
