Default USB bug fixes

There are 3 patches which are suggested by Sarah Sharp to be backported to older kernels like 3.2. *However, the 3.2 stable kernel tree doesn’t include these patches, thus Precise won’t have these bug fixes thru straightforward kernel upgrading.


*


1.******
8bea2bd usb: Add support for root hub port status CAS

Impact:

This patch fixes an issue with USB device connections not being detected after system resume from suspend.


*


2.******
622eb78 xHCI: Increase the timeout for controller save/restore state operation

Impact:*

This patch fixes an issue with failed system suspend and resume on platforms with the AsMedia xHCI host controller.

*


3.******
1530bbc xhci: Add new short TX quirk for Fresco Logic host.

Impact:

This patch fixes an issue with robotic-sounding audio under the Fresco Logic host controller.*

Thanks,

Yingying

Hi Yingying,

seems all three are in various versions of 3.2.y upstream

3.2.24 -> Ubuntu-3.2.0-29.45 (in proposed)

3.2.21 -> Ubuntu-3.2.0-27.42 (in updates)

3.2.19 -> Ubuntu-3.2.0-26.41 (superseded already)
