I discovered that my new Asus only had a USB input, so it needed a HUB that allows me to have permanently and the external hard drive and the ventilation system, installed on the laptop. But now, this Asus (unless it is Windows 8) it recognizes the HUB, does not recognize the elements I above branch ... I keep it for the case ... I discover the reason. Too bad, the length of the wire as the positioning of entrances suited me completely. !
