It looks like I may have signed-off a little too soon. While the patch is
working correctly if the Hauppauge Live2 is plugged in after the system has
booted and settled down (my normal use case), it fails if the Live2 is
plugged in while the system is booted up.
Unplugging the Live2 after recording (which appears to succeed from the
command line, but had no audio), executing lsusb just hangs.
I've included what I think is the relevant portions of /var/log/syslog
below. If you'd like the entire log file posted somewhere please let me
know.
Thanks,
Alistair
