[Solved] Unable to identify laptop webcam

Question

Hi all!
I bought my computer some months ago but never really needed the webcam untill now. I went to check the website of the shop that built and sold me the computer but was unable to find out what kind of webcam there is on my computer (I sent an e-mail).
I tried lsusb, lspci and lshw. Here are the output of lsusb and lspci:

A grep on hwinfo also gave that:

Thank you for any advice,

Post the output of
v4l2-ctl --all
(from v4l-utils) This is going to show us if your camera is being recognized as such, and if yes, which driver is in use, and what it can do. Your output will ideally be similar to this:
