I need more USB ports to my Pi2 v1, and so I want to use a passive USB hub for WL keyboard/mouse stick, WiFi stick, and perhaps a small 2.5" USB HD or a memory stick.
Will e.g. these 2 USB hubs or similar ones assumably work for those devices to my Pi2 USB ports?

Or will I have to purchase a powered active USB port instead?
