    The last time I was looking into USB 3 was before Ivy bridge came out and back then I heard that if you plugged a USB 2.0 device into the 3.0 port then all 3.0 ports would only run at 2.0 speeds, is this still true?

    also: M14X due to arrive the 15th, can't wait.

    Not all USB 3.0 ports just that port that the USB 2.0 is connected to

    It is just the USB 2.0 port, the USB 3.0 stay the same unless you plug a USB 3 device into the USB 2 port, that it will only run and cap at USB 2's speed. So I think you might have been misread that somewhere.

    Hmm, that i know. I think it had to do with the pre-ivy bridge chipset if anything. I was just worried that if i were to plug a USB 2.0 mouse into the 3.0 slot then it'd lose the other 3.0's speed. I can't recall where i read it, might of been Newegg on a motherboard review but that was a while ago.

    Thanks :)
