[Bug 1412121] Re: Hauppauge USB-Live2 fails on Haswell USB3 port


A kernel patch has been accepted that mostly resolves this issue:


This modifies the xHCI driver to apply a quirk (XHCI_AVOID_BEI) to all
Intel xHCI host controllers (previously the quirk was only applied to
one series of Intel controllers).  The patch affects all isochronous USB
devices, e.g. video and audio capture.

After applying the patch I'm able to record video as long as the Live2
is plugged in after the PC has booted.  If the Live2 is present during
boot, the failure is intermittent.  Our latest hypothesis is that this
is a bug in the cx231xx driver, not the xHCI driver. The current
behaviour is still a big step forward, allowing reliable recording, and
likely will resolve issues for a significant number of video and audio
capture devices connected to Intel xHCI host controllers, thus for now I
would mark this issue resolved and I'll submit another bug report if I'm
able to narrow down the outstanding issue(s).

I've successfully tested the patch against the following kernels:

* Mainline 4.0-rc5
* Mainline 3.19.2
* Mainline 3.19.3
* Ubuntu 3.19.0-10-generic

It looks like it will be kernel 4.1 before the patch makes it to general

Should I change the status from "Triaged" to "Fix Committed"?

  Hauppauge USB-Live2 fails on Haswell USB3 port

Status in linux package in Ubuntu:

Bug description:

  I've been attempting to capture video using a Hauppauge USB-Live2.
  This works fine in Ubuntu 14.04 on an older laptop that only has USB2
  ports, but fails on my Dell XPS13 which is USB3 with the Haswell

  The information in this bug report is based on Ubuntu 14.10 / Kernel
  3.16.0-29, however I have also tried it on a daily 15.04 image (3.18
  kernel) and using the upstream 3.19-rc4 kernel without success (the
  error messages change, and it does seem to be improving, but still
  fails to operate correctly).

  I'll attach an extract from /var/log/syslog that shows the following:

  1. Plugging in the Live2 - from 09:30:48 to 09:30:56
  2. Attempting to run mythffmpeg as shown below - at 09:31:33
  3. Terminating mythffmpeg with Control-C - 09:31:43
  4. Unplugging the Live2 - 09:32:47

  The command line was: mythffmpeg -y -loglevel debug -f alsa -i
  plughw:1,0 -f v4l2 -s pal -pix_fmt yuyv422 -i /dev/video1 -b:v 2048k

  Please let me know what other information you would like to see.
