Hi Jeff, Everything made it through just fine. I put together another script to run for more information. Can you use the same procedure? The script is available here: https://us-east.manta.joyent.com/rmustacc/public/tmp/uftdi.d If you save it to /var/tmp/uftdi.d, you'd run this as dtrace -s /var/tmp/uftdi.d -o /path/to/output/file. It may be worth filing a bug on github.com/joyent/smartos-live/issues, so we can better track this outside of e-mail.
