from some googling I think the Blue is USB 3.0, the Yellow is USB
2.0 always on, and black is normal USB 2.0. try lsusb and see if a USB 3.0
hub is listed. I am guessing at this because I have yet to work with USB 3
but I think it should be listed the same as USB 2.0. Your USB 3.0 hardware
may not be supported yet.
