Hi there, I'm currently working on a kernel module patch, adding support for the Microsoft Sidewinder X4 / X6 gaming keyboards. There are 30 dedicated extra keys on the Sidewinder X6, all sending out individual USB codes and 6 extra keys on the Sidewinder X4. Also, both devices feature 3 profiles for each of these extra keys, resulting in about 90 extra keys for the Sidewinder X6 and 18 for the X4. While picking 18 keycodes for the Sidewinder X4 is not a big issue (KEY_F13 - KEY_F24, KEY_WWW, KEY_EMAIL, KEY_PROG[1-4]), I'm having a hard time choosing something reasonable for the X6. These keys are (software) programmable and therefore don't need to have a function except sending out an individual, unqiue keycode. The problem I'm facing is not technical; it's more of a design question. With keyboards like the Corsair K90 / K95 (18 macro keys, 3 profiles each, total of 54 extra keys) or the Logitech G110 (12 macro keys, 3 profiles, 36 extra keys), there's need for dedicated, general keycodes for extra keys. So, I'd propose defining KEY_M1 - KEY_M100 (M for macro) in linux/input.h for such uses or extending the already defined F-keys up to KEY_F100. What are your thoughts about this?
