| * Human interface on XMEGA-B1 Xplain: | |
| * - RED led close to USB connector is always on after firmware startup | |
| * - Led 0 is on when USB line is in IDLE mode, and off in SUSPEND mode | |
| * - Led 1 blinks when USB Host have checked and enabled HID mouse interface | |
| * - Mouse move are linked at switches 0 (right), 1 (left), 2 (down), 3 (up) | |
| * - All switches can be used to wakeup USB Host in remote wakeup mode. | |
