Ubuntu 22.04 USB 不工作（使用电池供电时）

这是我之前问题。我以为tlp是哪里出了问题，于是停止了服务，然后它就正常工作了。但是当我尝试用电池运行笔记本电脑时，USB 设备再次无法工作。工作几秒钟后就停止了。

lsusb显示我的设备并dmesg

在tlp-stat

总线 001 设备 002 ID 413c:250e 控制 = 开启，自动暂停延迟毫秒 = -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 如上所述这里。

我对 Ubuntu 22.04 真的很失望。

答案1

经过漫长的调试时间，我找到了解决方案。它也与有关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

我必须设置RUNTIME_PM_ON_BAT=on，它最初设置为自动。
现在外部 USB 键盘和鼠标可以正常工作，并且电池没有问题。
