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,

Not always. Often pluging my usb key first results same
