Hello, Thank you for answering so quickly. Before using your sources (with Ubuntu 10.04 kernel), there was a lot of bug with my USB 3.0 card (unable to boot if the external hdd was connected to the USB3 card). Now everything seems to be working well, I can reboot without problem and the xhci_hdc driver is lunched at startup correctly if I'm not mistaken. The problem now is the speed; you saw a lot of bulk transfers because I was copying something in order to see the speed. I'm in USB 2 speed: 30Mo/s in average. Once I don't know why but I was at 70Mo/s. So to summarize the biggest problem is the speed and (I don't know if it is an error) the end of my dmesg: [186.240362] xhci_hcd 0000:02:00.0: @37809000 00000000 00000000 00000000 01033800 I don't know what means this line but there are a lot of them... Please feel free to ask me if you need other command outputs... Thank you again for your time. Best regards.

I see a lot of successful bulk transfers. On a high level, what is your issue?
