From b8d9cb970bc4f21217ca1f810a8f3a86312bb2d6 Mon Sep 17 00:00:00 2001 From: Jean-Francois Thibert Date: Wed, 9 Oct 2013 11:18:05 -0300 Subject: [PATCH] upstream: [media] Add support for KWorld UB435-Q V2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
