| 15 | * Roccat Kone is a gamer mouse which consists of a mouse part and a keyboard |

| 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? |
