[Bug 1242321] Re: USB 3.0 Harddrive not recognised


Indeed hardware might be buggy and special tweaks could be required in
drivers to recover functionality of any given hardware. But given we
cannot influence (usually) hardware manufacturers to fix stuff (or even
to do better stuff next time) the only thing we may do is to "improve"
Linux drivers so they allow us to use the hardware in question.

And this is all doable. But what really helps here is ability to capture
more lower-level logs (like with enabled dynamic debugging of usb/xhci
driver), ability to build and run Linux kernel with proposed
changes/patches. If above is ok for you just report your issue to USB
mailing list and let developers of USB drivers to help you. Info about
mentioned mailing list is available here - http://www.linux-

  USB 3.0 Harddrive not recognised

Status in linux package in Ubuntu:

Bug description:
  Ubuntu is not recognising any device plugged into any USB 3.0 ports.
  Sometimes Ubuntu will freeze for a few seconds when you plug something
  into a USB 3.0 port; when Ubuntu comes out of the freeze, the device
  is still NOT recognised.

  No problems with USB 2.0 ports and devices.

  The USB 3.0 on this computer only works in Windows 7 (I'm dual booting
  Ubuntu 13.10 and Windows 7, both are 64-bit).
