USB 3.0 port speed
My USB 3.0 ports won't go faster than 480 Mbps as this is the concentrator speed even if they should go much faster. Apple say that : " If you plug in a USB 2 hub first, all devices connected will operate up to the maximum transfer rate of USB 2 speed after that." It is possible to go back to USB 3.0 speed after you plugged a USB 2 first? I already tried to reset the PRAM and the SMC, it didn't work.
