Think what you want. But remember that the USB ports gets its
power after it has been stepped down to a working value from a
distant PSU. The amperage is more like 500 mA (milli-amps). And
how the front panel USB ports are connected will also determine
whether or not it is borrowing from the same 500 mA per port or
on its own line.
