当ADB服务器运行时，Syslog洪水泛滥

Question

我有一个linux框，每当我运行adb时，我都会注意到，大量的垃圾消息涌入系统杂物，例如：

Mar 09 17:22:39 laptoo kernel: hub 1-0:1.0: hub_resume
Mar 09 17:22:39 laptoo kernel: hub 1-0:1.0: port 1: status 0507 change 0000

Mar 09 17:22:40 laptoo kernel: ehci-pci 0000:00:1a.0: GetStatus port:1 status 001005 0  ACK POWER sig=se0 PE CONNECT

我只有在我输入adb kill-server之后就消失了。有没有办法在ADB服务器运行时摆脱它们？

Answer 1

增加USBCORE AUTOSUSPEND值。首先检查当前值

  cat /sys/module/usbcore/parameters/autosuspend

然后，将其更改为您想要的东西。或者，如果愿意，可以将其设置为-1：

  echo -1 > /sys/module/usbcore/parameters/autosuspend

注意：这将防止在任何USB设备上进行自动刺激。
