위의 메시지는 공유기에 USB to Serial을 연결했을 때 나오는 커널 메시지 입니다.

아래와 같은 순서를 가지고 이동합니다.

usb_alloc_arb -> usb_init_urb -> usb_submit_urb -> usb_get_urb->usb_unanchor_urb->usb_free_urb->usb_free_urb->urb_destroy

대충 요약하자면 urb를 할당하고 초기화 하고 전송요청을 보내고 urb를 링크드리스트에서 제거하고 urb를 삭제시키고 객체 참조를 감소시키고 있는데요

이해가 안가는데 urb를 보내고 받는 과정이 없는 것 같은데, 원래 이런 과정이 있어야 하는 것 아닌가요??

아니면 제가 printk를 어딘가 해주지 않은 부분이 있어서 출력이 안된 것일까요???
