well ive got my nano working but a page comes up that says im plugged into a 1.0 usb instead of a 2.0. seems to work fine. is there any way i can upgrade my power mac g4 digital audio to a 2.0. im plugged into a self powered 4 port hub, even when i used the 5 volt adapter it said it was 1.0 on the hub. does anyone know if my ports on the back of my computer are 2.0 or are they 1.0. if i buy a 2.0 hub am i going to get 2.0 at the ipod or am i stuck with whatever is coming out of the computer. if the ipod nano is working now should i just leave best enough alone.
