From 6dbea9f0978fc47e26aaf1fd4246e63160b778a6 Mon Sep 17 00:00:00 2001 From: Jean-Francois Thibert Date: Wed, 9 Oct 2013 11:18:05 -0300 Subject: [media] Add support for KWorld UB435-Q V2 This patch adds support for the UB435-Q V2. You might need to use the device once with the Windows driver provided by KWorld in order to permanently reprogram the device descriptors. Thanks to Jarod Wilson for the initial attempt at adding support for this device.
