 * Roccat Kone is a gamer mouse which consists of a mouse part and a keyboard

 * part. The keyboard part enables the mouse to execute stored macros with mixed

 * key- and button-events.

 *

 * TODO implement on-the-fly polling-rate change

 *      The windows driver has the ability to change the polling rate of the

 *      device on the press of a mousebutton.

 *      Is it possible to remove and reinstall the urb in raw-event- or any

 *      other handler, or to defer this action to be executed somewhere else?

 *

 * TODO is it possible to overwrite group for sysfs attributes via udev?
