Fix USB initilaize on LUFA
- Add print messages of USB intialize procesure. - call out sei() in earlier stage. LUFA API doc of USB_Init() says: interrupts must be enabled within 500ms ... to ensure that the host does not time out whilst enumerating the device - remove matrix_init() from suspend_wakeup_init(). It is not needed in fact and if matrix_init() takes long time to initialize it prevents host emnumerating the device.led_matrix
