Error code: -1, errno: 2, error: No such file or directory

Hi there!

I got this error when running "chicony-ir-toggle on" or "chicony-ir-toggle off".
Also tried running it as root, same error here.

I have an ThinkPad X380 Yoga.

Any idea how to fix this?

Thanks,

Judging from your USB device identifier 04f2:b605 your camera is a different model than mine 04f2:b67c. What's your laptop model? Have you tried it on other devices than /dev/video2?

Maybe this discussion boltgolt/howdy#269 will help you dig deeper into the problem.

I'm having the same issue on my Leveno X1 Carbon 8th Gen.
The thread in your link was mostly confusing.
I'm not very familiar with these things, but I'd gladly provide any info you need to fix the problem :)

Same problem here! With a Lenovo ThinkPad P1 3th Gen. I tried also with the video0, and is the same mistake. But I am sure that the IR cam is the video2.

I allow myself to advise you to have a look at my repo https://github.com/EmixamPP/linux-enable-ir-emitter. It's more or less a fork of this one except that I changed the debugging because as you can see the errors are not adapted to the situation. I took the opportunity to write a complete tutorial on how to modify the PetePriority code to adapt it to your camera.

Perfect! Now, it is working.
Thank you!
