Fel*_*hes 5 usb devices power-management
我买了一个 USB 灯,我想使用命令打开/关闭它(我的目的是设置一些 CRON 作业以在特定时间打开它)。
\n我研究了几个答案,但没有一个有效。
\n我尝试使用所有 USB 端口(包括 USB 集线器中的端口等)输出到 、 工具,但没有任何/sys/bus/usb/drivers/usb/unbind效果/sys/bus/usb/devices/usb1/power/level。uhubctl
该灯是一个哑设备,当它插入端口时它就会打开。
\n我的电脑是MouseComputer Co.,Ltd. MB-R500.
灯就是这个。

我能够把它关掉。解决方案:
uhubctl工具(使用 进行安装sudo apt install uhubctl)。我买的HUB就是这个(System Talks出品的Sugoi HUB,型号:USB2-HUB4X-BK)。我不确定它是否仍在生产,但还有其他可以工作的(这是受支持的集线器的非详尽列表)。
就我而言,我使用此命令(阅读文档)来切换开/关:
sudo uhubctl -l 1-1 -p 1 -a toggle

显然,其他设置的数字会有所不同。
