Not just the potential of that happening, but the host mayn't be able to
supply the amount of current desired (not a voltage drop, per se, but a
supply issue - if the host was only designed to supply "so much," then
that's all it's going to give).  Whereas a powered hub has its own
specifications, which may support more power.
