usb

I have a Thinkpad E430 notebook, and the intel's USB 3.0 controller can not be recognized by Ubuntu 12.04.

The LED on my USB-HDD is white instead of blue (And in Windows 7, it is blue when connected to USB 3.0 port, and is white when connected to 2.0). And the transfer speed is around 25MB/s instead of 65MB/s in Windows 7.

I'm not familiar with Linux systems, so I've no clue about what's going wrong. I've searched the web, but got no solution.
