USB-이더넷 어댑터는 잠자기 모드인 것처럼 주기적으로 작동을 멈춥니다.

내 노트북은 유선 연결을 위해 USB-이더넷 어댑터를 사용합니다. 활발하게 작업하는 동안 주기적으로 연결이 끊어집니다. NetworkManager는 DHCP를 통해 연결하고 IP 주소를 얻으려고 시도하지만 매번 실패합니다. 케이블이 분리된 것처럼 USB 이더넷 어댑터의 연결 표시등이 꺼집니다. (케이블은 괜찮습니다.) USB 이더넷 어댑터를 뽑았다가 다시 연결하거나 노트북을 다시 시작하는 두 가지 방법으로 문제를 해결할 수 있습니다. 둘 다 단기적으로 작동하지만 이 문제는 몇 시간마다 무작위로 발생합니다.

ip link set dev eth0 down그럼 ip link set dev eth0 up퍼포먼스를 해라아니요작동하지만 NetworkManager가 여전히 IP 주소를 얻을 수 없습니다. 두 개의 서로 다른 이더넷 어댑터에서 문제를 관찰한 결과 어댑터에 문제가 있을 가능성은 거의 없습니다. 노트북은 비교적 새 제품이고 USB 포트에 문제가 있을 가능성은 거의 없어 보입니다. 적극적으로 작업하는 중에 문제가 발생하는 것으로 보아 전원 관리와는 명백히 관련이 없는 것 같습니다.

동일한 증상을 재현할 수 있었습니다(UGREEN 브랜드 AX88179 기가비트 이더넷 어댑터는 모든 패킷의 tx/rxing을 중지하고 결국에는 표시등이 꺼지고 ip link명령으로는 작업을 다시 수행하기에 충분하지 않습니다). 하지만USBDEVFS_RESET ioctl() 시스템 호출을 사용하여 소프트웨어에서 어댑터를 성공적으로 재설정할 수 있었습니다.

ioctl() 시스템 호출을 보내려면 Debian의 명령줄 도구를 사용 usbreset하거나usbutilsioctlhttps://github.com/jerome-pouiller/ioctl.

각 AX88179(ID는 0b95:1790)를 재설정하려면 usbreset다음을 실행하세요.

sudo usbreset 0b95:1790

또는 이 유틸리티를 사용하려면 다음을 수행하십시오 ioctl.

% lsusb |grep AX88179
Bus 002 Device 002: ID 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet

% sudo /usr/local/bin/ioctl /dev/bus/usb/002/002 USBDEVFS_RESET
Decoded values: ioctl=0x00005514, direction=NONE, arg size=0 bytes, device number=0x55 ('U'), function number=20
Used values: ioctl=0x00005514, direction=NONE, arg size=0 bytes, device number=0x55 ('U'), function number=20
Returned 0

lsusb명령은 버스 및 장치 ID(002 및 002)와 ioctl()을 보낼 파일을 결정하는 데 사용됩니다 /dev/bus/usb/002/002. 파일 시스템을 사용해야 하는데 /dev/bus/usb여기에 있는 내용은 /sys/bus/usb여기서는 도움이 되지 않습니다.

이것은 Debian Buster arm64, 커널 5.10.17-v8+에서 작동합니다.
