Package: src:linux
Version: 3.16.7-ckt20-1+deb8u3
Severity: important

I am using a ThinkPad L450 with an integrated USB camera:

Bus 002 Device 004: ID 5986:055a Acer, Inc

uvcvideo detects the camera but fails to initialize it:

[    2.428694] uvcvideo: Found UVC 1.00 device Integrated Camera (5986:055a)
[    2.428801] uvcvideo: No valid video chain found.
[    2.428877] usbcore: registered new interface driver uvcvideo

Consequently, guvcview fails with the message that no video device has been
found.

The problem has already been reported, among others, to Ubuntu [1] and 
to the
linux-uvc mailing list [2].  On the latter, the post from 2016-01-08 
provides
a patch that fixes the problem.

If this patch meets quality standards, I'd be in favor of applying it.
