I mean that nothing happens, the USB 3.0 ports doesn't do a thing. For example: When I hook my USB flash drive into a 2.0 port, the led will be on, the computer will do that sound that windows does any time you plug a USB device, the explorer window will automatically open, etc. When I try the same flash drive (or, my iPhone for example) into the port 3.0 nothing happens, no iTunes opening, no windows sound, no led, nothing.
