* Human interface on EVK1100 : | |
* - PWR led is on when power present | |
* - 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 buttons are linked to switch PB0 (left), PB1 (middle), PB2 (right) | |
* - Joystick are used to move mouse | |
* - Only Push joystick button can be used to wakeup USB Host in remote wakeup mode. | |
