Small case, usb recognition 1 and 2 and usb ports (7) for each device, each port overload indication (7) LED lit (good), LED off (bad) .Mauvais connection or lack voltage .Very good hub .By comparison with my old hub, with lots of helpful but not LED disco, and the indication usb 2 usb 1 when in reality, and recognitions of random devices, D-Link 7-Port Hub is a great produit.Je advises, it is without problems.
