The Hub is doing what he should. He turns a USB port four. However, he lit while the whole room. The blue LED is so bright that you better not look directly at the current device without safety goggles. I have it taped directly. In addition, there is something badly thought that. Each on the short sides of the unit of current or USB B connector So it is with the cable guide a little difficult, because just on both short sides a cable is plugged in. Would not buy me the device one more time, it keep but because the purchase price does not justify a return.
