USB 切换器不允许从挂起状态唤醒

我有两台笔记本电脑（和两台 Raspberry pi）连接到 4 路 USB 交换机，一个键盘和鼠标作为所有四台设备的输入设备。当我挂起笔记本电脑（一台是 ubuntu，另一台是 xubuntu）时，我无法使用键盘或鼠标唤醒它们。我尝试按照grep . /sys/bus/usb/devices/*/power/wakeup此处的说明启用所有设备的唤醒功能@Pavlos Theodorou 的问题并发现这将适用于最近暂停的设备，但如果我按下切换器上的按钮将其更改为其他设备，则暂停的设备将被唤醒。有人有使用 USB 切换器的经验吗？

我遇到了类似的问题。您应该能够直接启用键盘，而无需启用 KVM。您还必须启用它所连接的 USB 端口。例如 /etc/udev/rules.d

# Enable usb port 3 wakeup
ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0001", ATTRS{busnum}=="3", ATTR{power/wakeup}="enabled"
# Disable KVM wakeup
ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ATTRS{idVendor}=="0557", ATTRS{idProduct}=="7000", ATTR{power/wakeup}="disabled"
# Disable mouse wakeup
ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ATTRS{idVendor}=="1ea7", ATTRS{idProduct}=="0064", ATTR{power/wakeup}="disabled"
# Enable keyboard wakeup
ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ATTRS{idVendor}=="1c4f", ATTRS{idProduct}=="0047", ATTR{power/wakeup}="enabled"

按此顺序执行的原因是因为第一条规则会自动启用附加到它的所有内容。
