Disable Logitech BRIO Infrared Camera on Linux with udev
2026-03-16
Linux exposes the Logitech BRIO webcam's infrared (IR) camera as an additional webcam (/dev/video$N). This is confusing, as the wrong "Logitech BRIO" camera is often selected by default.
The following udev rules, e.g. in /etc/udev/rules.d/logitech-brio.rules, can be used to disable the IR camera:
ACTION=="add", SUBSYSTEM=="video4linux", ENV{ID_USB_MODEL}=="Logitech_BRIO", ATTR{index}=="2", RUN+="/usr/bin/rm $env{DEVNAME}"
ACTION=="add", SUBSYSTEM=="video4linux", ENV{ID_USB_MODEL}=="Logitech_BRIO", ATTR{index}=="3", RUN+="/usr/bin/rm $env{DEVNAME}"
Add the rules and reload udev. Next time the BRIO is plugged in the IR camera should no longer appear.
sudo udevadm control --reload-rules
