First off hubs don't support a lot of power hungry devices so you should be able to buy an optional power adapter for the hub on targus' site. Second if your computer doesn't have any usb 3 ports then the hub will only operate at usb 2 speeds.
Your probably overloading the hub. Buy the power adapter.
