Linux 主机总是不经意被鼠标移动唤醒，本篇记录如何禁止此种特性。
USB 键鼠套装，类型为 Logi。查看 usb 并过滤关键字
$ lsusb | grep -i logitech
Bus 001 Device 005: ID 046d:c534 Logitech, Inc. Unifying Receiver
有两块信息需要记录
$ udevadm info --attribute-walk --name /dev/bus/usb/001/005
looking at device '/devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3.1/1-3.1.1':
KERNEL=="1-3.1.1"
SUBSYSTEM=="usb"
DRIVER=="usb"
ATTR{authorized}=="1"
ATTR{avoid_reset_quirk}=="0"
ATTR{bConfigurationValue}=="1"
ATTR{bDeviceClass}=="00"
ATTR{bDeviceProtocol}=="00"
ATTR{bDeviceSubClass}=="00"
ATTR{bMaxPacketSize0}=="8"
ATTR{bMaxPower}=="98mA"
ATTR{bNumConfigurations}=="1"
ATTR{bNumInterfaces}==" 2"
ATTR{bcdDevice}=="2901"
ATTR{bmAttributes}=="a0"
ATTR{busnum}=="1"
ATTR{configuration}=="RQR29.01_B0016"
ATTR{devnum}=="5"
ATTR{devpath}=="3.1.1"
ATTR{idProduct}=="c534"
ATTR{idVendor}=="046d"
...
ATTR{power/wakeup}=="enabled"
...
新建配置文件 /etc/udev/rules.d/logitech-unifying.rules，其内容为
ACTION=="change", SUBSYSTEM=="usb", DRIVERS=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c534", ATTR{power/wakeup}="disabled"
与 udevadm 查看到的内容一致。匹配 usb 设置 id 修改 attribute
power/wakeup为 disabled
$ sudo udevadm trigger
# check again
$ udevadm info --attribute-walk --name /dev/bus/usb/001/005
现在看到的 power/wakeup 应该为 "disabled"。此时可以休眠电脑并进行测试
