Here is the output of usbctl -f /dev/usb1 -a 2. (The BisonCam is a different built-in webcam that works.) Someone pointed out that the Logitech may have a microphone built in that makes it come up as uaudio. But even then it doesn't work--comes up as /dev/uaudio0 in the log, but "ls /dev/uaudio0" says it doesn't exist.
