USB hub uses two ports but no external power
However, you’ll need to give up two of your existing USB ports in order to get three new ones plus a mini-USB connection. So this device will appeal to some people but not others.
I’d actually use it because I have exactly two USB ports on my laptop and I currently use a powered USB hub to hook up a keyboard, a mouse, charge my phone via mini-USB, and occasionaly hook up an iPod or digital camera. Holy crap, this thing is perfect for me! What am I waiting for?
