USB-Ethernetアダプタは、スリープモードのように定期的に動作を停止します。

私のラップトップは、有線接続にUSB-Ethernetアダプタを使用しています。積極的に作業している間、定期的に切断されます。 NetworkManagerはDHCPを介して接続し、IPアドレスを取得しようとしますが、毎回失敗します。ケーブルが外れているかのように、USBイーサネットアダプタの接続インジケータが消えます。 (ケーブルは大丈夫です。)USBイーサネットアダプタを抜いて再接続するか、ラップトップを再起動する2つの方法で問題を解決できます。どちらも短期的に動作しますが、この問題は数時間ごとにランダムに発生します。

ip link set dev eth0 downそれではip link set dev eth0 upパフォーマンスをしなさいいいえ動作しますが、NetworkManagerはまだIPアドレスを取得できません。 2つの異なるイーサネットアダプタで問題を観察した結果、アダプタに問題がある可能性はほとんどありません。ノートブックは比較的新製品であり、USBポートに問題がある可能性はほとんどないようです。積極的に作業している間に問題が発生しているため、電源管理とは明らかに関係がないようです。

機能しないから動作への切り替え(アダプターの切断/再接続)を含むログ出力が大きすぎて、関連性のないログエントリを削除した後でも、質問に直接含めることはできません。ここで見つけてください。https://paste.ee/p/f5OFZ

答え1

同じ症状を再現することができました(UGREENブランドのAX88179ギガビットイーサネットアダプタは、すべてのパケットのtx / rxingを停止し、最終的にはインジケータが消え、コマンドで操作を再ip link実行するのに十分ではありません)。 しかし、USBDEVFS_RESET ioctl()システムコールを使用して、ソフトウェアでアダプタを正常にリセットできました。

ioctl() システムコールを送信するには、Debian のコマンドラインツールを使用するusbresetか、usbutilsioctlhttps://github.com/jerome-pouiller/ioctl

各AX88179(IDは0b95:1790)をリセットするには、usbreset次の手順を実行します。

sudo usbreset 0b95:1790

または、このユーティリティを使用するには、次の手順を実行します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

このlsusbコマンドは、バスとデバイスID(002と002)とioctl()を送信するファイルを決定するために使用されます/dev/bus/usb/002/002。ファイルシステムを使用する必要がありますが、ここ/dev/bus/usbにあるものは/sys/bus/usbここでは役に立ちません。

これはDebian Buster arm64、カーネル5.10.17-v8+で動作します。
