Seems like weird error in V4L subsystem or in uvcvideo driver, in the most standard usage scenario. Please retry with kernel and FFmpeg as new as possible, best if compiled from latest upstream sources. For kernel please try release 4.7.2 or even linux-next (git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git), for FFmpeg please make a git clone from git://source.ffmpeg.org/ffmpeg.git and there do "./configure && make" and run obtained "ffmpeg" binary. Please CC me when you come back with your results.
