Can't find laptop built-in camera

Question

I am running arch and try to use my built-in camera. Unfortunately any program I started can't detect it. I guess the needed drivers are not installed.

I run arch linux on my computer, with the most recent updates. I checked my camera with a live usb drive of Ubuntu, and there it worked out of the box. Can I check there somehow which drivers I would need?

How can I detect it?

This is the output of lsusb:

Edit

I found a more detailed data sheet, it specified the camera with this: CAMERA HD W/2MIC L80SR. Googling this didn't help me much further unfortunately.
