Ironically, there seem to be more reports of laptop USB external bus-powered drives not working with USB 2.0 power than USB 1.1 power. Well, at least anecdotally.Originally posted by: AIWGuru
High power devices = 220 mA
Low power devices = 100 mA or less
500mA total power per port.
USB 1.1=3.33v
USB 2.0=5.0v

USB2.0 highspeed != USB2.0 full speed
highspeed = another name for USB1.1
