USB 장치(키보드 또는 마우스)가 "lsusb"에 표시되지만 두 번째 USB 장치가 연결된 경우 작동하지 않습니다.

지난 몇 달 동안 랩톱에 연결된 두 번째 USB 장치가 표시되고 lsusb괜찮아 dmesg보이는데도 응답하지 않는 이상한 문제가 발생했습니다.

USB 마우스와 USB 키보드 모두에 해당됩니다. 어떤 장치를 먼저 연결하든(어떤 USB 포트에 연결하든 상관없습니다) 즉시 인식되어 제대로 작동합니다. 연결할 두 번째 장치도 표시되지만 lsusb입력 dmesg에 전혀 응답하지 않습니다.

lsusb키보드(정상 작동)와 마우스(응답 없음)가 연결된 출력은 다음과 같습니다.

확인해 보니 설치된 커널 버전이 시스템을 마지막으로 부팅한 버전과 다르지 않은 경우 이 오류가 계속 발생합니다.

[mindtree@mindtree ~]$ uname -r
4.18.12-arch1-1-ARCH
[mindtree@mindtree ~]$ pacman -Q linux
linux 4.18.12.arch1-1

노트북이 연결되어 있을 때와 연결되어 있지 않을 때 모두 이런 현상이 발생합니다.

두 장치를 모두 연결한 상태에서 컴퓨터를 다시 시작하면 안정적으로 감지되며, 그놈에 로그인하면 두 장치 모두 응답합니다.

가끔이 오류는 전혀 발생하지 않지만 꽤 자주 발생하며 이유를 알 수 없는 것 같습니다. 예를 들어, 지금은 오류가 더 이상 나타나지 않지만 마지막으로 오류를 뽑았다가 다시 연결한 이후로 해당 텍스트 상자에 입력하는 것 외에는 시스템에서 아무 작업도 수행하지 않았습니다.

내 노트북은 Arch Linux 및 Gnome 3.30.1을 실행하는 Razer Blade Stealth입니다.

이는 적어도 gdm-x-session 로그가 주장하는 내용에 대한 추가 정보를 제공합니다 no input driver specified, ignoring this device. 이 버그를 조사하고 다시 보고하겠습니다.
