[Resurrecting an old thread, and assuming a better solution hasn't already been found...]

Yesterday I had opportunity to use an external USB 3.0 drive with the released CentOS 6.2 LiveDVD (booting from a USB stick) to make an image of my laptop's internal drive, which is beginning to show pre-failure signs (reallocated sector count is high).

The CentOS 6.2 Live media's kernel (which should be the same as the SL Live media's kernel once the SL Live media is released) found and used the Wester Digital external USB 3 drive on my generic USB 3.0 ExpressCard controller perfectly, and the image took about the same amount of time, 4.5 hours, as an eSATA image to a similar drive using an ExpressCard eSATA controller.  This is half the time that a USB 2.0 image had taken a few months ago.

So this issue should be resolved fully with the SL 6.2 kernel, if a 6.1 kernel has not already resolved it.
