joydev: Keyboards incorrectly identified as joystick

Or, really: "Keyboards incorrectly say they're a joystick". Some keyboard like to say they have joystick capabilities while they don't. This results in a joystick device showing up (e.g. in games) that is not calibrated and just generally messes things up. This seems to happen with multiple keyboards, mostly from Microsoft: e.g. the Microsoft Digital Media Pro Keyboard and Microsoft Wired Keyboard 600. Earlier reports on this mailing list: http://thread.gmane.org/gmane.linux.kernel.input/25913 http://thread.gmane.org/gmane.linux.kernel.input/25926 Downstream bug reports: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/987877 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/390959 evtest output for certain keyboards: https://launchpadlibrarian.net/112444244/evtest2 http://pastebin.com/tX4nnhAg It would be easy to add an exception to joydev_match() like there currently are for touchpads, tablets, etc. The question is: what should the test be? Or should this be handled in userspace (udev)? Jethro Beekman
