From 52f1f2303f131d6d287a5316e35a4ec0d8ac8b98 Mon Sep 17 00:00:00 2001 From: Frank Schaefer Date: Wed, 27 Mar 2013 17:06:35 -0300 Subject: [PATCH] [media] em28xx: add comment about Samsung and Kodak sensor probing addresses MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Windows driver also probes at least two further i2c addresses (0x22 >> 1 and 0x66 >> 1). I've got some hints that they are very likely used by Samsung and Kodak sensors, which are known to be used in Empia devices, too. We havn't seen any devices using these sensors yet and don't know how to probe them properly, so leave a comment.
