S3C2440 S3C2450 보드에서 USB 사용시 에러
2011.09.22 06:13
제가 사용하는 보드는 2450을 사용하지만 드라이버 보니 2410과 2440과 거의 같이 사용하는거 같아서
분류를 2440쪽으로 올리게 되었습니다.
이번에 보드의 USB를 동작하게 위해서 커널 환경을 맞추어서 드라이버는 올라오는거 같은데
USB 메모리스틱을 연결하니 "-62"가 포함된 에러메시지들이 연속적으로 출력됩니다..
참고적으로 /proc/devices 은 다음과 같습니다.
인터넷을 검색해보아도 -62 에러 메시지가 나오는 경우는 거의 없는거 같더군요..
해결방안을 아시는 고수님들 답변좀 부탁드립니다.
