Most recent kernel where this bug did not occur: None Distribution: Ubuntu Hardware Environment: Any xbox-type DDR pad. Software Environment: Use jstest to test functionality. Problem Description: The dance pads I'm using require that the up and down, or left and right buttons be hit simultaneously. If the directional buttons are interpreted as axes, this is impossible. To fix, USB IDs for dance pads should trigger different behavior; also, it should be possible to pass an option to the driver to force DDR-type behavior (axes mapped to buttons), as well. There have been patches available for this behavior, but they are out of date. The following is a patch for 2.6.11.4 that implements the above-described behavior for a slightly earlier API. http://einsteinsbreakfast.com/demos/xpad-mappings.diff
Care to forward port that patch, and/or get the original author of it to do so and send the linux-usb-developers? It needs to be in the form specified in Documentation/SubmittingPatches.
The patch was signed off, in modified form, by Dmitry Torokhov, Andrew Morton and Greg Kroah-Hartman and reposted to the LKML. It's in the mainline kernel now: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=deb8ee43a23d48116cb23eb8dd1de2348efb1e80
