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,
Hi Christopher,
Thanks for the clarification, I'm looking forward to when this works
its' way through to the Ubuntu kernel.
Thanks again,
Alistair

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

Another USB device crash, this time caused by try to format an external
disk with gparted. Probably not the same bug, but I'm passing it on to
the kernel maintainers.

Hi Christopher,
Would you please let me know why you added the bios-outdated-a06 tag?
I updated the bios just before originally submitting this bug to confirm
that it wasn't fixed by the BIOS. A06, dated 22 Dec 2014, is the
latest offered by the Australian Dell website.
Thanks,
Alistair

This kernel successfully records video and audio for the first time
using the xhci stack, but usb locks up afterwards (lsusb never returns).
See attached syslog.

Alistair,
Yes please report this upstream to linux-usb and alsa-devel. Thanks!
We'd be more than happy to include and resulting fixes in Ubuntu.

I've already received confirmation from the original author of the
Hauppauge USB-Live2 USB driver that there are problems with the device
on the xHCI stack, see:
After a bit more testing, accidentally selecting the wrong video device
and successfully recording video from the built-in webcam and audio from
the Live2, I think it is reasonable to say that the ALSA errors in
syslog from mainline 3.19rc5 are due to problems between the Live2
drivers and the

I tried 3.19.0-031900rc5-generic from the mainline builds. I'm able to
get further this time in that I can record something, however you can
see errors in syslog, attached below. I think the relevant events are
at:
16:47:02 - system boot (I think)
16:48:16 - plug the Live2 in to the USB port
