Hi Alan,

There is a tar file[0] attached to the bug report[1].  The tar file
contains a few examples of failed and successful recording attempts
while collecting usbmon traces.  There is a readme.txt file available
after extracting the files.

The bug reporter states that only the first recording after boot fails.
Subsequent recordings succeed will succeed.

Thanks again for reviewing this, Alan.  Just let me know if you would
like any additional data or testing.

Thanks,

Joe

I have replied to the original report at bugs.launchpad.net with a
diagnostic patch.  Maybe it will help indicate what's going wrong.
