[Bug 1507868] Re: No external USB with Linux 3.19.0-30-generic


Aaron Staley, the next step is to fully reverse commit bisect from
kernel 4.3-rc6 to 3.19 in order to identify the last bad commit,
followed immediately by the first good one. Once this commit has been
identified, then it may be reviewed as a candidate for backporting into
your release. Could you please do this following

Please note, finding adjacent kernel versions is not fully commit

Thank you for your understanding.
