USB 设备断开连接/触摸板关闭

  • 772

我这里有一台东芝 Z20T-C 敞篷车，运行 Ubuntu 19.04，内核 5.0.0-29。几天/几周以来，可拆卸键盘底座（底部）中的触摸板、键盘背光和 USB 端口在启动到桌面后几乎立即停止工作。触摸屏和键盘继续工作。所有设备和端口都在 BIOS 菜单中工作，所以我会排除硬件缺陷。当我分离/重新连接扩展坞时，键盘灯短暂闪烁，触摸板工作几秒钟，然后又死了。我尝试关闭 usbcore 的自动挂起（内核引导参数中的 usbcore.autosuspend=-1 并更新 grub）。这有助于在屏幕关闭之前。之后，触摸板又死了。还尝试在 powertop 中为某些 USB 设备切换电源设置，但这没有帮助。
断开/重新连接扩展坞时 dmesg 告诉我：

完整的 dmesg 日志在这里。

编辑 1：我使用“udevadm monitor”来检查设备死机时会发生什么。它打印：

所以似乎内核关闭了集线器

编辑 2：我尝试将“acpi=off”添加到内核启动模式参数，并回滚到内核 5.0.0-13，但它没有改变任何东西。我还尝试添加一个 UDEV 规则文件“/etc/udev/rules.d/99-powersave.rules”：

ACTION=="add", SUBSYSTEM=="usb", ATTR{power/control}="on"
ACTION=="add", SUBSYSTEM=="usb", ATTR{power/autosuspend}="0"
ACTION=="add", SUBSYSTEM=="usb", ATTR{power/autosuspend_delay_ms}="-1"
ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="1", ATTR{power/control}="on"
ACTION=="add", SUBSYSTEM=="usb", ATTR{busnum}=="2", ATTR{power/control}="on"

但这也无济于事。我现在完全不知道下一步该尝试什么。

编辑 3：我现在已经尝试过内核版本 4.18.20、5.0.21 和 5.2.21，但没有任何运气。这可能是 udev / acpi / 驱动程序问题，但我不知道去哪里找......

  1. 这个答案有许多 USB 自动关机设置要检查：

    经过几天的挣扎，我设法在 Ubuntu 17.10 上找到了解决方案。希望这适用于所有在使用 D6000 坞站时遇到问题的人。下面的格式是markdown（懒得转换它）

    在 Ubuntu 中修复坞站问题上的空白监视器的说明。

    确保更改后重新启动！

    禁用 USB 自动挂起
    • sudo gedit /etc/default/tlp并将以下值从更改1为0
    USB_AUTOSUSPEND=0
    • sudo gedit /etc/udev/rules.d/01-usb-dock.rules. 这将创建一个新文件。

    禁用显示电源管理
    • sudo gedit /etc/X11/xorg.conf将以下选项附加到文件中。
    Section "Monitor"
Identifier "DVI-I-3-2"
Option "DPMS" "false"
EndSection

Section "Monitor"
Identifier "DVI-I-2-1"
Option "DPMS" "false"
EndSection
    禁用音频暂停
    • sudo gedit /etc/pulse/default.pa. 注释掉下面指示的行。
    ### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle
    在 BIOS 中禁用 USB 唤醒

    开机时按 F12 键进入 BIOS。在Power Management>>下USB Wake Support取消选中两个框。

    就我而言，这毕竟是硬件缺陷。在某些时候甚至键盘都死了，所以我更换了整个键盘/底座部分。现在一切都恢复正常了，所以这不是 Linux 问题......
