It would be nice to know how this part works. I've seen log messages about USB problems, and XTension's attempts to restart. But if I remember correctly there is a specific number of retries. Does XTension then just give up, or does it retry again at a later time?

This all becomes important in trying to figure out how to power the system assuming there will be outages. My serial devices (CM11 and several W800) come off a powered USB hub. Do I need to provide backup power to that hub along with the computer? Or better yet is there a script that would retry the USB when line voltage returns?
