Hi, 1.7.3 won't work with kernels >=3.16, you will need a newer version, uvcvideo suffered a regression that will only be fixed (hopefully) in 3.18, the developer already posted a patch to fix it. I'll make a new release (2.0.1) in the next couple of days with a workaround for this. you will need this version to get guvcview up and running with uvcvideo devices.
Note: libv4l2 (1.4.0 and 1.5.0) is also broken, a fix is expected in 1.6.0, but you will be able to disable its use in guvcview in this version.
