I turned off the Pi while away for a week. When I came back the camera was no longer working.
Camera model
Dorhea Camera Module Automatic IR-Cut Switching Day/Night Vision Video Module Adjustable Focus 5MP OV5647 Sensor 1080p HD Webcam
What is the problem?
While webcamd seems to load fine (on port 8080) based on the log, the stream isn't available. I get a "connection refused" error when I attempt to connect to port 8080.
What did you already try to solve it?
I've tried turning on and off the interface in raspi-config as well as many reboots. Sometimes I get a different error in the logs that looks like something else is using the camera but I can't see anything that is.
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
This is the last two boots from the webcamd you can see the two different results. Neither one was working.

There should be no problems with USB (a.k.a. select() timeout)
