* The wrapper function basically wraps tud_task and some log.

* If you have more requirements for this task, you can create your own task which calls tud_task as the last step.

* @retval ESP_OK run tinyusb main task successfully
* @retval ESP_FAIL run tinyusb main task failed of internal error
* @retval ESP_ERR_INVALID_STATE tinyusb main task has been created before
