이 재설정을 해결하는 방법은 무엇입니까?
데비안 서버입니다. 콘솔/시스템 로그에 지속적이고 반복되는 메시지가 있습니다:
kernel: usb 1-7.4: reset low-speed USB device number 4 using xhci_hcd
이 장치는 IPMI의 가상 키보드와 마우스인 것으로 알고 있습니다. IPMI를 재설정한 후 다음과 같은 로그 항목이 나타나지만 잠시 후 문제가 다시 발생합니다.

이는 다시 재설정되지만 IPMI 재설정 후 할당된 새 장치 번호를 반영합니다.

이것이 출력입니다 lsusb. IPMI 구성 요소는 USB 전용 장치입니다.
