After using the integrated webcam, it never fully turns off and keeps hogging the battery. From powertop:

The battery reports a discharge rate of 22.6 W
The estimated remaining time is 0 hours, 41 minutes

Summary: 369.6 wakeups/second,  60.7 GPU ops/seconds, 0.0 VFS ops/sec and 7.9% CPU use

            Usage       Events/s    Category       Description
          100.0%                      Device         USB device: Laptop_Integrated_Webcam_HD (CN0T3NPC724871BBK5P1A00)
           11.8%                      Device         Display backlight
            5.7 ms/s      58.1        Process        /usr/bin/pulseaudio --start --log-target=syslog

How can I properly turn it off? All the tunables are "good."

It's a Dell V131. I don't know about the camera. This is the only device I cannot account for in lsusb output:
