如果 USB 适配器未重新连接，鼠标移动将唤醒睡眠中的系统

我有 /etc/udev/rules.d/99-wakeup.rules 来禁用使用连接到设备的键盘或鼠标时从睡眠状态唤醒：

ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ATTRS{idVendor}=="0a81", ATTRS{idProduct}=="0205", ATTR{power/wakeup}="disabled"

USB 设备

$ lsusb | grep 0205
Bus 001 Device 006: ID 0a81:0205 Chesen Electronics Corp. PS/2 Keyboard+Mouse Adapter

我添加GRUB_CMDLINE_LINUX="udev.log-priority=debug"了 /etc/default/grub 并运行sudo update-grub以提高日志级别。重新启动并运行

$ LC_ALL=C journalctl -b0 -u systemd-udevd | grep -F /etc/udev/rules.d/99-wakeup.rules

但重启后

$ cat /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1.1/power/wakeup
enabled

什么会将其更改为“启用”？即使鼠标移动也会将系统从睡眠状态唤醒。但是，如果我在启动后重新连接适配器，该值将变为“禁用”。我希望该规则在启动时也有效。如果这是一个错误，应该针对哪个软件包报告此错误？

我可以通过在进入系统暂停之前写入（可能自动）来解决此问题（disabled参见）。/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1.1/power/wakeupman systemd-sleep
