Default Etron USB 3.0 controller

From: AceLan Kao<acelan.kao@canonical.com>

SRU Justification:

Impact: This only affects the Etron USB 3.0 controller.
When insert USB 3.0/2.0 device into any of the USB 3.0 port, device will not
be recognized. And the dmesg shown as below.
[ 58.330621] usb 3-1: Cannot reset HCD device state
[ 58.590690] xhci_hcd 0000:05:00.0: Unknown completion code 192 for reset device command.

Fix: Patches taken from upstream kernel

Testcase: Tested on ACER machine

Maarten Lankhorst (2):
xhci: Do not issue device reset when device is not setup
xhci: Add defines for hardcoded slot states

I cannot determine from your patch header or the bug report which
release you are targeting.


Patch 2/2 seems unnecessary unless you are planning on more patches in
this area.

Dear Tim,

Sorry, it's for Natty kernel.
And the patch 2/2 is needed by patch 1/2, since patch 1/2 uses the
keyword SLOT_STATE_DISABLED which is defined in patch 2/2.

Best regards,
AceLan Kao.

We would hope to see those coming back through stable upstream. I would like to
see them applied the opposite order as the dependency goes that way.
