I'm not sure if this is of any help, but I've had trouble with Suyin webcam on my Asus laptop running the 3.16.0-31 kernel. Kernel 3.13.0-37.64 worked well...
Here is the hw id: Bus 001 Device 003: ID 064e:9700 Suyin Corp. in skype the video screen from me and remote was black and I noticed error libv4l2: error dequeuing buf: Invalid argument and guvcview didn't show any video either. It was just flooding the console with "Ignoring empty buffer ..." messages. I've tried testing ppa from Paulo and after installing the following packages: ii guvcview 2.0.1+ubuntu2~ppa1+1278-0ubuntu0~201501091246~ubuntu14.04.1 amd64 GTK+ base UVC Viewer ii libguvcview-1.0-1:amd64 2.0.1+ubuntu2~ppa1+1278-0ubuntu0~201501091246~ubuntu14.04.1 amd64 GTK+ base UVC Viewer - runtime the problem magically went away - in skype too.. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1362358 Title: uvcvideo doesn't work with USB webcam with linux 3.16 Status in The Linux Kernel: Unknown Status in linux package in Ubuntu: Triaged Bug description: uvcvideo doesn't work with linux 3.16 on at least two USB webcams. guvcvideo shows a black screen and reports "Could not grab image" or "ignoring empty buffer".
