| 69 | * Apple Bluetooth Magic Mouse driver |
| 70 | * |
| 71 | * The Apple Magic Mouse is a HID device but it doesn't provide a proper HID |
| 72 | * descriptor, and requires extra initializations to enable the proprietary |
| 73 | * touch reports. We match against the vendor-id and product-id and provide |
| 74 | * our own Bluetooth connection handling as the bthidev driver does not cater |
| 75 | * for such complications. |
| 76 | * |
| 77 | * This driver interprets the touch reports only as far as emulating a |
| 78 | * middle mouse button and providing horizontal and vertical scroll action. |
| 79 | * Full gesture support would be more complicated and is left as an exercise |
| 80 | * for the reader. |
| 81 | * |
| 82 | * Credit for decoding the proprietary touch reports goes to Michael Poole |
| 83 | * who wrote the Linux hid-magicmouse input driver. |
| 84 | * |
