please have a look at https://bugzilla.kernel.org/show_bug.cgi?id=81611 Due to a change in the driver, guvcview won't work with kernel 3.16. You have to revert up to two kernel commits or use the latest version of guvcview (git version >2.0.0) regards Dominik Kopp -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
