내 SD 카드가 인식되지 않는 이유는 무엇입니까?

저는 VAIO 노트북에서 Lubuntu 11.10을 사용하고 있습니다. 이것은 내 uname결과입니다.

Linux vaio 3.0.0-16-generic-pae #28-Ubuntu SMP Fri Jan 27 19:24:01 UTC 2012 i686 i686 i386 GNU/Linux

이유는 모르겠지만 오늘 SD 카드가 작동하지 않았습니다. 플러그를 꽂으면 아무 일도 일어나지 않습니다.

몇 가지 팁을 시도해 봤습니다여기하지만 아무것도 아니야. 내 폴더 sdf에는 아무것도 없습니다 /dev.

출력은 다음과 같습니다 lspci.
