I could not figure out which one is the webcam. So, I looked into the output of
lspcias well; but nothing there either. So, I was having a hard time figuring out which device is my webcam. The other question running in my head was the rare possibility of my kernel not detecting my webcam. I checked out
/var/log/dmesg.logto see if it was detected. I ran the following
grep webcam /var/log/dmesg.log
I was disappointed to find nothing. After some time, I realized my mistake and tried the grep query in case insensitive mode.
grep -i webcam /var/log/dmesg.log
This time I found the device.
uvcvideo: Found UVC 1.00 device Laptop_Integrated_Webcam_FHD (05ca:181c)
input: Laptop_Integrated_Webcam_FHD as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.5/1-1.5:1.0/input/input8
Looking at the output I tried loading the uvcvideo kernel module and tested the webcam with the following vlc self-recording command.
vlc v4l:// :v4l-vdev="/dev/video0"
It worked fine. So, I looked into the Arch wiki for more details. It mentioned that
linux-uvcwas now in kernel. Looking into a more exhaustive list of devices supported by uvcvideo, I found the following matched my device closely.
So, I guessed 05ca:181c should also be supported by
uvcvideobut being a new model was not listed there. So, I have reported this to the dev team and added the module
uvcvideothe list of modules in my
MODULES=(acpi-cpufreq cpufreq_ondemand cpufreq_powersave uvcvideo)
Interestingly it is a Ricoh device but the driver is not the Ricoh driver [mentioned in the wiki].
