Picked THIS little raspberry pi powered hub as a great starter hub setup. It works great with my walmart onn device. Can run xbox usb or generic usb (wired or wireless) controllers, bluetooth dongled mouse or keyboard. will also run wired mouse and keyboards. it can only handle chargers up to 5v or up to 5.2 volt chargers, but I happened to have a spare laying around that works a treat. Set the hub to OTG mode and enjoy! (the micro usb female plug is what you would use for the charging port and is perfectly fine to leave plugged into a wall adapter for a constant power source). Setting the hub in charge mode disables otg if I'm not mistaken.
