First your only relevant crash is the most recent and we cant draw any conclusions from just one. One thing of note is that your uptime (the time since your last boot) is at least 8 straight days, and rises to almost 18 days.
You can alleviate many of this type of driver issue by rebooting at least every second day.
We are going to have to wait for the next one and hope it is not in the distant future so we have something to compare this one to.
It is a driver power state failure and the evidence points to something related to USB.
