Hi Matt, Did you read this post? http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg17269.html It seems the card needs some soldering :( Cheers Igor > > >> -- > >> To unsubscribe from this list: send the line "unsubscribe linux-media" > >> in the body of a message to majordomo@xxxxxxxxxxxxxxx > >> More majordomo info at http://vger.kernel.org/majordomo-info.html -- Igor M.
