A USB bus can provide a maximum total current of only 500 mA to all devices (maximum 127). If the power consumption of the already connected devices is close to the 500 mA limit, each additional USB device that wants to use the power supply of the bus can overload the bus and thus disable it. This cannot happen with the dLAN® duo.
