Although, people don't usually use more then two devices at a time unless they have a hub of course. Actually power is the big obsticle. But the needed power for a set of headphones would not be great. Just understnad that if you want a speaker you triple the size and power requirements. Audio output is the main power consumption. And in a portable situation you would only be looking for the single USB device anyway. ======= Kirk Wood Cpt.Kirk at 1tree.net Nothing is hard if you know the answer or are used to doing it.
