| TheDarkBender said: You can use USB 3.0 devices/sticks, although when using a usb hard drive (not a stick) you need to have an AC adapter or a second usb cable to power the device, because the Wii U won't let you use a HDD that uses one usb cable for power and data. |
that is because new portables are USB 3.0
you will need a Y cable. usb mini b to USB or mini usb to USB depending on the connector type.
Best is to get one on AC power.
