내 Linux 커널(여기서는 여러 가지 기본 2.6, 3.2 및 3.5와 사용자 정의 3.7.3 커널을 시도했습니다)이 내 시냅틱스 터치패드를 감지하지 못합니다. 또는 너무 멍청해서 찾을 수 없습니다. 내가 조사한 것은: dmesg, lsusb -v, lspci -v, lshw, /dev/input, /dev/bus/00x/(...)
두 개의 내부 USB 루트 허브와 통합 속도 매칭 허브, 펜 드라이브 및 광 마우스가 표시되었지만 그 외에는 관심이 없었습니다.
이제 질문에 관해서는: 사용 가능한 드라이버가 없으면 커널이 일부 하드웨어를 감지하지 못할 가능성이 있습니까? 내가 이해하는 바에 따르면 커널은 적어도 일부 하드웨어 주소에서 알 수 없는 장치를 보고해야 합니다.
