    I have first rMBP model and have a little issue with USB and wondering if anyone else have a same issue.

    When I connect a USB 3.0 device first before any other USB devices, my rMBP recognize it well but if I ended up connecting any one of my USB 2.0 devices first and connect a USB 3.0 device, USB 3.0 device is recognized as USB 2.0 device.

    Has anyone experienced same issue and is there any fix for it?

    Yeah I can connect USB 3.0 device first but it is darn annoying to unmount every USB 2.0 drives to connect 3.0 device again.

    Thanks,
