I have only one webcam. But I am using a virtual camera via OBS Studio.
AFAIK, the v4l2-ctl command gets its information from the device and/or driver in use by the device.
Do you know if the loss of focus_auto happen recently? If so, try booting to a previous kernel to see
if a kernel change may have triggered it.
FWIW, the webcam of my laptop has ceased working. Old age. And I only have a USB Capture HDMI
device on my desktop that does create both a /dev/video0 and /dev/video1.
