ASUS ROG G14 (2022) Ryzen 6000 authentication issues with camera + IR

[sayantandas]

Hi there, I am facing issue when trying to authenticate using Camera + IR. The authentication is not working all the time. I have to try more than 4-5 times to get a success. When I use only the camera , authentication is much faster and hits close to 100% success rate. My setup

 v4l2-ctl --list-devices

    /dev/video1

I have tried linux-ir-emmitter

 sudo linux-enable-ir-emitter configure
INFO: Ensure to not use the camera during the execution.
INFO: Warning to do not kill the process !
Is the ir emitter flashing (not just turn on) ? Yes/No ? Yes
ERROR: Your emiter is already working, skipping the configuration.
ERROR: The configuration has failed.
INFO: Do not hesitate to visit the GitHub ! https://github.com/EmixamPP/linux-enable-ir-emitter/wiki

I have tried the following troubleshooting steps from arch wiki https://wiki.archlinux.org/title/Howdy#Testing_your_IR_camera

The camera at /dev/video0 produces 8 images which I can view using an image viewer

gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=10 ! image/jpeg ! multifilesink location="frame-%02d.jpg"

Got EOS from element "pipeline0".
Execution ended after 0:00:00.582118200

However, it fails to produce anything in /dev/video2

Please help me toincrase the success rate for camera + IR

It's my Asus Rog 14 2022 howdy config settings. Try it.

But my kernel 6.0.9-060009-generic, and it works well

I used the signed kernel from jammy-proposed as I did not remove the secure boot. Your setting seems to work fine. I was able to get it working in most scenarios. Thank you.

I believe, that the device you want to use is actually /dev/video1 At Least it is on my G14.
