I make it a module and I ran into more problems. It seemed to load the firmware but Kaffeine says there is no video device. http://pastebin.com/ABVWVrma It seems to print a lot. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
