From 1ca31892e3af05ad3a72769e3c922cca3cde4f9d Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 27 Nov 2009 13:49:48 -0200 Subject: [PATCH] em28xx: em2800 chips support max width of 640 Due to hardware limitation, em2800 chips can't work at resolutions higher than 640x576, since the URB packet size is not enough. The effect is that the image looses packages and shows a distortion along the vertical axes.
