1. For use in a high-speed serialized bus protocol device having a plurality of ports capable of transferring both data and electrical power, apparatus for dynamically allocating the distribution of the electrical power over said plurality of serial ports, comprising:

  • a power controller, the power controller pre-programmed with an optimal efficient power use value;

    a first module configured to determine an amount of electrical current drawn over a first portion of said plurality of serial ports; and

    a second module configured to adjust an amount of current available to a second portion of said plurality of serial ports, said adjustment being based at least in part upon the amount of current drawn over the first portion of said plurality of serial ports and the optimal efficient power use value of the power controller when the high-speed serialized bus protocol device is not plugged into an external power source.
