저는 USB-이더넷 변환기를 사용하여 노트북을 Raspberry Pi에 연결하고 있습니다. 그러나 커널 로그에는
USB: device descriptor read/64, error -71
나는 이전에 이 장치를 아무런 문제 없이 사용해 왔습니다.
lspci및 의 출력과 함께 전체 로그 출력은 lsusb다음과 같습니다.

이에 따르면블로그 게시물, 하드웨어 문제일 수 있습니다. USB 장치는 과도한 전류를 끌어올 때 자체 보호를 시도할 수 있습니다.
다른 케이블을 사용해 보거나 컴퓨터를 끄고 기다렸다가 다시 켜는 등 제안되는 해결 방법은 다양합니다.
