Ah... you said 'Driving Force'.. not 'Driving Force Pro', but given the confusing naming schemes I think I can be excused :-) http://en.wikipedia.org/wiki/Gran_Turismo_official_steering_wheel#Model_comparison However I do remember that there's a quirk with the logitech wheels that they all pretend to be the same device, but some can be sent a magic command which makes them disconnect and re-connect with a different USB ID and with the larger steering range. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=drivers/hid/hid-lg4ff.c;h=d7947c701f3063ac6c3683c29d3eca333b7ca1b0;hb=8b31849a113a8868eb2de692be5c9ecadae93ac9#l549 So in summary we need to be careful with "046d:c294 Logitech, Inc. Driving Force" Personally I have a Driving Force Pro, Driving Force Wireless and a G27 which all start with reporting this ID. So a couple of questions: 1) Are you sure you have a "Driving Force"? 2) Does the ForceFeedback work for you? Just for reference we moved the FF for the logitech wheels to hid-lg4ff back in Aug 2011, I'm not sure which mainline kernel that was... http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=history;f=drivers/hid/hid-lg4ff.c;h=d7947c701f3063ac6c3683c29d3eca333b7ca1b0;hb=8b31849a113a8868eb2de692be5c9ecadae93ac9 Simon -- 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
