Yup, it's 100mA by default for all ports (1.1 and 2.0) unless something (Windows driver, Linux kernel module, OSX....module? what do the OSX people call their stuff) takes control and increases the flow. I'm still trying to noodle out how this pin 2 trick works in relation to what I know of the code and working with the linux guys which is all software based... I wonder almost if it's "dual mode" in that one mode is for the charger (which relates to the pin2 trick here) and one is completely software driven. It sounds semi-reasonable...
