When I try to connect a USB 3.0 device in Ubuntu 12.10 (ASUS K55VD, kernel 3.5.0-19-generic #30-Ubuntu SMP), the system says

[   74.747832] hub 3-0:1.0: unable to enumerate USB device on port 1
[   74.931957] usb 4-1: new SuperSpeed USB device number 2 using xhci_hcd
[   74.949390] usb 4-1: New USB device found, idVendor=05e3, idProduct=0731
[   74.949396] usb 4-1: New USB device strings: Mfr=0, Product=1, SerialNumber=2
[   74.949400] usb 4-1: Product: USB Storage

[   75.038700] usbcore: registered new interface driver usb-storage
[   75.038701] USB Mass Storage support registered.

but it does not recognize the device, and the disks applications (gparted, nautilus) act as if nothing had been connected. I have checked other questions, but either they have no answers or they told about previous Ubuntu version with 3.0.x kernels.

A USB 2.0 device will work in the USB 3.0 ports. A USB 3.0 device will work (at USB 2.0 speeds) in the USB 2.0 ports. The problem, as I wrote, is between USB 3.0 devices and USB 3.0 ports.

I have my USB 3.0 ports configured without legacy support via the BIOS (the way they should be, I suppose). But I also have tried to configure them with XHCI Preboot mode disabled.

Have any one solved a similar problem? Thanks in advance.

@EnesKuray, the USB 3.0 device works in windows 7 and windows 8. I have edited my question. Here is more information: "A USB 2.0 device will work in the USB 3.0 ports.

can you update kernel to 3.6.6? –  user84277 Nov 16 '12 at 14:37
    
Which feature has 3.6.6 that beats 3.5.x? Is there any repository available? Or do I need to compile it? –  fernando garcía Nov 16 '12 at 15:44
    
usb support is about kernel . upubuntu.com/2012/11/install-linux-kernel-366-in-ubuntu.html –  user84277 Nov 16 '12 at 16:20

If the following does not work then I suggest you read How do I report a bug?

Some users have reported the same issues on Windows 7 & Windows 8. The solution was doing the first 2 steps provided in here which were basically:

  1. Update the BIOS

  2. Make sure that in the BIOS (After upgrading it) you check that in Advanced -> Chipset -> Southbridge the option USB 1.1 OHCI Controllers and USB 2.0 EHCI Controllers are "enabled". Of course, there are a couple of K55VD Models, so this applies to some of them.

The general idea is to do the steps for the BIOS. If it works great. If not, you have just found a bug my friend. So file the bug using the link above and a developer will help.
