From 02bc1f5574e7324c03c49b3d2892e9e404d777be Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 3 Mar 2014 16:28:39 -0300 Subject: [PATCH] [media] em28xx: add support for Kworld UB435-Q version 3 This device is close to Kworld UB435-Q, but it uses a different tuner. Add support for it. Tested with both 8VSB and 256QAM modulations.
