There should be no difference, according to the USB standard. In order for USB devices to work on an extremely wide variety of machines (from laptops to desktops, Dell to HP to Apple, etc) the standard dictates exactly how the USB port should act, including how much power is available, the transfer rate, protocol, etc. For any device with a USB output, that standard is going to be followed.
