Ubuntu 22.04 USB 无法工作（使用电池运行时）

  • 772

这是我之前问题的延伸。我认为tlp是罪魁祸首，于是停止了服务，结果成功了。但是，当我尝试使用电池运行笔记本电脑时，USB 设备再次无法工作。工作几秒钟然后停止。

lsusb显示我的设备和dmesg

在tlp-stat

总线 001 设备 002 ID 413c:250e 控制 = 打开，autosuspend_delay_ms = -1000 -- 戴尔计算机公司戴尔激光鼠标 MS3220 (usbhid)

我曾尝试安装linux-hwe-22.04、停止tlp、配置 tlp，如此处所述。

我对 Ubuntu 22.04 真的很失望。

    经过几天的调试，我找到了解决方案。也与tlp.

    在/etc/tlp.conf文件中。

     Runtime Power Management for PCI(e) bus devices: on=disable, auto=enable.
# Default: on (AC), auto (BAT)

RUNTIME_PM_ON_AC=on
RUNTIME_PM_ON_BAT=on

    必须要设置RUNTIME_PM_ON_BAT=on，本来是设置自动的。
    现在，外部 USB 键盘和鼠标可以正常工作，不会出现电池问题。
