purchased to connect a mouse and keyboard on a laptop very light, easily recognized by the computer as soon as the driver who search on the internet (what will happen if this one n '(not connected)? to report no power LED you can connect a mouse and a keyboard that also will be a Driver (even if they are already known to the computer by direct connection) by against external HDD does not work (they surely they need a docking station or a self powered hub is on) I think that we should not attempt to connect a USB key or camera to download, for all those uses prefer direct USB connection So hub cheap, light and perfect for little greedy devices must not ask him what he can not do
