I'm not getting any /dev/video* devices from any of my old and new Logitech usb cameras.

lsmod shows me nothing v4l2 related.
modprobe -c | grep v4l2 returns nothing.

Iv'e tried various update commands but none seem to be installing any v4l2 kernel drivers.

Can anyone tell me how I can install the v4l2 kernel drivers?

Cheers!

UPDATE2: I believe that for some reason my system is missing 'v4l2-core'. I downloaded the kernel source and it's there in,

 ubuntu-focal/drivers/media/v4l2-core

Iv'e tried to compile it but no luck so far.

you mixed up something v4l2 is a framework/applicaton for comtrolling videocameras not a module for your camera. Please [edit] your question and show us `sudo lshw -c multimedia`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
