I've spent a lot of time trying to figure out why my USB 3.0 doesn't work on Ubuntu 13.04, but I was not able to find the answer. So I have decided to post this question here now.

The port on my VAIO T ultrabook is definitely getting power, but no device is recognized when I plug it in.

I could post any other outputs here if needed. I appreciate your help!

Do you have any BIOS/UEFI settings related to the USB ports? –  ubfan1 Aug 18 '13 at 19:51

Can you post the output from the dmesg|tail command just after the usb device is plugged? –  Prarobo Nov 20 '13 at 17:37

Have you tried Ubuntu 14.04 yet? –  HarlemSquirrel May 7 at 17:00
    
Check your BIOS settings and make sure those ports are enabled. –  BackTRanito May 9 at 22:27
