The sysinfo output you gave should be enough for me to whip one up. Go ahead and file a bug at https://github.com/linuxwacom/libwacom/issues with a link to your wacom-hid-descriptors bug in case somebody else gets to it before me. If I don't get to it myself in the next few days, please do poke me :) Jason --- Now instead of four in the eights place / you’ve got three, ‘Cause you added one / (That is to say, eight) to the two, / But you can’t take seven from three, / So you look at the sixty-fours.... -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
