What is a pity is the fact that the stroke does not have an ON / OFF switch. My WD MyBook external hard drive no longer turns off when I connect through the hub. Connected directly to the notebook will switch off when you shut down the operating system itself off. The same applies to my scanner, which is supplied only with "USB power". It always seems to be a small voltage is applied to the connected equipment to bear. When referring to drive me is relatively unimportant, because I can turn this. The scanner I do not use too often to shut it only when you need to - as I have done it before.
All in all a very good, reliable stroke, I would recommend anyone who is up to 7 (actually sinds yes 6) requires additional USB ports.
