Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  trusty on Intel NUC, xc5000 firmware load kills all USB

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  Intel NUC D54250WYK, kernel 3.13.0-23-generic x86_64, Trusty 14.10,
  package linux-firmware-nonfree 1.14ubuntu1

  Installed and updated trusty 2 days ago, also updated select libs
  yesterday trying to debug this issue.  Issue seems to be with firmware
  load and the usb subsystem.   When Hauppauge 950Q inserted to usb
  port, kernel sees it and reports what appears to be normal device
  recognition.  As soon as an application tries to access the Hauppauge
  device, there are problems.  Two examples can make it fail repeatedly.

  Fail case #1) 
  With Hauppauge inserted into usb port, as root, run lsusb -v
  it aborts when trying to ennumerate the Hauppauge device.

  Bus 002 Device 004: ID 2040:7200 Hauppauge 
  lsusb: gconv.c:74: __gconv: Assertion `outbuf != ((void *)0) && *outbuf != ((void *)0)' failed.
  Aborted (core dumped)

  This failure is non-harmful as the USB bus is still active and devices
  plugged into usb still function.

  Fail case #2) 
  With Hauppauge inserted, run VLC and choose to capture the video device.

  VLC runs, kernel reports the firmware load starting, and completing.
  As soon as firmware load completes, the USB bus and all devices
  plugged in there are cut down.  Unplug and replug USB devices has no
  effect, and additional usb plug events are not seen or reported by
  kernel.  Power off to recover.

  Tried debugging a little.  The linux-firmware-nonfree package provides
  dvb-fe-xc5000-1.6.114.fw, but the kernel asks to load a newer version,
  dvb-fe-xc5000c-4.1.30.7.fw.  I got newer version from kernellabs.com
  and tried it.  Behavior is the same.

  Note- this device is known to work.  I have it working in ubuntu 11.10
  32bit, and in ubuntu 12.04 64bit.

  My kyb, mouse, and network card are all usb.  Do not have a wired
  ethernet connection to gain access (via ssh) after usb goes away..
  Will get that today but I don't know where to focus debug effort next.
  Gladly assist with additional debug.
