I got a new laptop Thinkpad E550 and at first the touchpad was not working so I updated the kernel but now the webcam is not working. Cheese is giving the error "device not found"

$ lsusb

Can you paste the output of lsusb in your terminal (Ctrl + Alt + t), and paste the result back here by editing your question? – P.-H. Lin Aug 19 '15 at 4:00

There is a bug for your webcam, it seems that it's not supported yet:
Acer, Inc ID 5986:055a is useless after 14.04.2 installed

Please subscribe to that bug to get you updated.
Also, you can click on the This bug affects # people. Does this bug affect you? string to state that you're affected by this as well.

Or you can patch it by yourself with a patch (ignore_chining_errors.patch) provided in:
http://sourceforge.net/p/linux-uvc/mailman/message/34182460/

By following instructions here to build your own kernel.

I subscribed to the bug, but I dont know how to patch it and fix it(if thats what you meant) Can we download this version of ubuntu, this shows that webcam will work ubuntu.com/certification/hardware/201411-16167 – sarthak agarwal Oct 6 '15 at 13:48
    
No, the camera for that pre-installed ThinkPad Edge E550 is "CHICONY Electronics Co Ltd Integrated Camera", which is different from yours. – P.-H. Lin Oct 6 '15 at 15:49
    
@sarthakagarwal This issue is now fixed in Xenial / Yakkety -proposed kernel, it should be available in updates two weeks later! – P.-H. Lin Dec 23 '16 at 7:19

I had the same kind of problem with cheese. So, I've installed GTK UVC Video Viewer and its features are also good.

You can install it via terminal by using this :

sudo add-apt-repository ppa:pj-assis/ppa
sudo apt-get update
sudo apt-get install guvcview
