hi, i test my Pinnacle PCTV USB2 for video acquisition on an A10S card,
the image kernel don't includes V4L2 support (em28xx) for this module so i compiled a kernel (3.4.67+) with the support .
the first test displayed a green image and select error with mplayer
after few research , this problem is the same for all arm processor (this thread http://www.raspberrypi.org/phpBB3/viewtopic.php?f=38&t=48599 (http://www.raspberrypi.org/phpBB3/viewtopic.php?f=38&t=48599) described the solution for rasberry pi) it's link to the line
height >>= norm_maxh(dev);
it shall be replaced by
height = norm_maxh(dev) >> 1;
compile , replace the original module and it works !!!
