Further information:  The patch has been back-ported to mainline 3.19.5,
and the mainline 3.19.6 kernel appears to have further improved the
situation, so that booting with the Live2 plugged in also works.  I
can't be sure that the problem won't happen again, as it appears to be
timing related, however it is certainly much better.

Title:
  Hauppauge USB-Live2 fails on Haswell USB3 port

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Hi,

  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
  chipset.

  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
  a.nut

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

  Thanks,
  Alistair
