I have the Kiyo connected to a raspberry pi. After doing the following changes the Kiyo is not working anymore:
v4l2-ctl -d /dev/video0 --set-ctrl=focus_automatic_continuous=0
this command did work. autofocus was disabled
v4l2-ctl -d /dev/video0 --set-ctrl=focus_absolute=255
this command workes aswell
v4l2-ctl -d /dev/video0 --set-ctrl=focus_absolute=0
after doing this command the camera is not working anymore.
as soon as a program wants access to the camera picture the camera crashes and completely disconnects from usb. this also happens under windows and macos. I updated the firmware, which didnt help aswell.
In linux I get the following error:
[ 8.782898] uvcvideo 1-1.4:1.1: Failed to set UVC probe control : -32 (exp. 26).
