That driver will work with any UVC compatible camera, so if your laptop camera is a USB camera that is UVC compatible (and almost all of them are these days), then I'd expect it to work.
Under Ubuntu (and probably other distributions as well), you can use guvcview to check: if that works with your camera, then libuvc_cam should as well.
guvcview has nothing to do with ROS, it's a Linux tool for interfacing with UVC compatible cameras. The only reason I mentioned it is because you can use it to make sure your camera is UVC compatible. The fact that guvcview can't find your camera suggests it is not. But ..
.. do you still have Windows on this machine? If so, does the webcam work there? It's rare for webcams to not be USB devices these days, but it is still possible. Try to find out what kind of webcam it is (look at the hardware properties fi), then you could try to set it up under Linux.
Also: a "driver" for ROS is nothing more than a small program that on one side knows how to 'speak ROS', and on the other side can talk to the real, OS-level, driver of your hardware. So the first thing to do is make sure your OS can work with your device. Then worry about ROS.
It very much looks like you don't have any video device, which would explain why you can't get any of the nodes to work (the fb0 device is an output device, not a camera). The usb_cam package suggested by @bluehash essentially does the same things as libuvc_cam, so also won't work.
I can help a little on the ROS side.
I've used usb_cam. The best way to test it on your laptop is to clone the github repo to a src folder in your catkin workspace. Change the video port in the launch file to whatever port your webcam is on. If an integrated camera is used, /dev/video0 should work. I use an external one, for which I use /dev/video1
All you have to do is a catkin_make and launch the node via:
roslaunch launch/usb_cam-test.launch
A video window should open. There will be a list of topics braoadcasting video data. I use /usb_cam/image_raw.
Edit: Tested in ROS Kinetic.
Hi Bluehash, thank you for the response! I cloned usb_cam and was able to catkin_make the package no problem. However, when I try to run the launch I get this error:
" Cannot identify '/dev/video0': 2, No such file or directory "
Is there a Linux command to see devices?
This package works fine for me and does not require to compile from source:
