"The usb port in question has a "battery" icon next to it, so my guess was that it is a powered port or a charging port. It is located on the laptop, not on my usb hub."

This is an "always-on" USB port. You can connect a device to charge it with the laptop battery even if the computer is "off/sleep/hibernate/whatever". Basically it lets you use your $2000 laptop as a very heavy and cumbersome $20 battery pack. :)
