USB 3.0 以太网适配器不工作 — Ubuntu 18.04

Question

我最近为我的笔记本电脑购买了一个新的以太网适配器，但它总是无法连接到互联网。我没有碰过我的网络设置（一切都设置为自动），我知道 USB 端口可以工作（并且是 3.0），我已经关闭了以太网电缆，并且我已经重新启动，但问题仍然存在。我查看了几个类似的问题，但没有看到答案。以下是一些相关命令的输出：

适配器接口是第一个，enx00e04c6880050。

\n\n

适配器是 Realtek 设备。dmesg这是;的一些输出 还有很多，但都一模一样。

我也跑去dmesg找司机；这是上面未显示的仅有的两行：

\n\n

~$ dmesg | grep r8152\n[    2.833638] usbcore: registered new interface driver r8152\n[    3.144927] r8152 1-2:1.0 eth0: v1.09.9\n

\n\n

编辑：我尝试谷歌搜索“Tx status -71”，我感觉这个\xe2\x80\x94 这似乎是一个未解决的错误 \xe2\x80\x94 是相关的，尽管我不完全确定如何实施提供的补丁，或者是否可以解决问题。

Answer 1

此内核参数为我解决了同样的问题（使用 Dell DA200 USB3 坞站）：

usbcore.quirks=0bda:8153:k

这会禁用设备的链路电源管理。另请参阅此错误报告和此Github 问题（对于具有相同驱动程序/NIC 芯片的不同硬件）。

Answer 2

这在 Ubuntu 18.04.4 下有效。可以在下面创建一个服务

/etc/systemd/system/dell-quirks.service

包含以下内容：

[Unit]
Description=Install quirks for DELL TypeC ethernet/VGA/ DA 200 adapter
Documentation=https://askubuntu.com/questions/1081128/usb-3-0-ethernet-adapter-not-working-ubuntu-18-04

[Service]
Type=oneshot
RemainAfterExit=true
#ExecStart=/usr/bin/echo 0bda:8153:k > /sys/module/usbcore/parameters/quirks
ExecStart=/bin/bash -c "echo 0bda:8153:k > /sys/module/usbcore/parameters/quirks"

[Install]
WantedBy=multi-user.target

重新加载守护进程

systemctl 守护进程重新加载

启用该服务，使其在每次重新启动时启动

systemctl 启用 dell-quirks.service

启动服务

systemctl 启动 dell-quirks.service

必须创建接口配置。在创建接口配置之前，可以为以太网接口指定一个名称

/etc/udev/rules.d/70-persistent-net.rules

包含以下内容：

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",ATTR{address}=="<MAC address of the ethernet interface>",ATTR{dev_id}=="0x0",ATTR{type}=="1",KERNEL=="eth*",NAME="eth0"

以太网网络配置可以通过创建 yaml 文件使用netplan完成

/etc/netplan/01-network-card.yaml

包含以下内容：

network:
  version: 2
  renderer: NetworkManager
  ethernets:
    eth0:
      dhcp4: true

当笔记本电脑启动时，断开 USB 设备的连接，启动后连接它，几分钟后它应该可以工作。如果需要，请重新启动NetworkManager并等待几分钟。

systemctl 重新启动网络管理器
