Not waiting for you!

Only works in the end than USB 2 on Macbook Pro Retina (last generation).
At first no worries then comes a time when you decide to connect your hard drive in addition to a USB stick and then error message indicating a lack of power. That's no problem using the USB cable provided to address this need energy which becomes annoying because this uses my two USB ports on the computer to use the box ...
Anyway admit this permit still spend 4 port but then nothing helps slow connections the box does not know where to turn. Too bad it's a nice well-finished product in hand but unfortunately does not hold all its advertised promises.
