15 | * Roccat Kone is a gamer mouse which consists of a mouse part and a keyboard | ||
16 | * part. The keyboard part enables the mouse to execute stored macros with mixed | ||
17 | * key- and button-events. | ||
18 | * | ||
19 | * TODO implement on-the-fly polling-rate change | ||
20 | * The windows driver has the ability to change the polling rate of the | ||
21 | * device on the press of a mousebutton. | ||
22 | * Is it possible to remove and reinstall the urb in raw-event- or any | ||
23 | * other handler, or to defer this action to be executed somewhere else? | ||
24 | * | ||
25 | * TODO implement notification mechanism for overlong macro execution | ||
26 | * If user wants to execute an overlong macro only the names of macroset | ||
27 | * and macro are given. Should userland tap hidraw or is there an | ||
28 | * additional streaming mechanism? | ||
29 | * | ||
30 | * TODO is it possible to overwrite group for sysfs attributes via udev? | ||
