Detailed Description

USB device: a keyboard and an absolute mouse.

Warning: you can only instantiate one instance of a USB device: USBMouse, USBKeyboard, USBAbsMouse, USBMouseKeyboard, or USBAbsMouseKeyboard.

Example: 

 #include "mbed.h"
 #include "USBAbsMouseKeyboard.h"

 USBAbsMouseKeyboard key_mouse;

 #define STEP (1000)

 int main(void)
 {
   int32_t a = X_MIN;
   int32_t dir = STEP;

   while (1)
   {
       key_mouse.move(a, a);
       key_mouse.puts("Hello From Mbed\r\n");

       if (((a+dir) > X_MAX) || ((a+dir) < X_MIN))
       {
           // Change direction
           dir = -dir;
       }
       a += dir;
