USB交换机不允许从挂起中唤醒
USB交换机不允许从挂起中唤醒
提问于 2022-08-10 13:27:58
我有两台笔记本电脑(和两台Raspberry pi)连接到一个4路usb交换机上，其中一个键盘和鼠标连接为所有四台电脑的输入设备。当我挂起笔记本电脑(一台是ubuntu，另一台是xubuntu)时，我不能用键盘或鼠标唤醒它们。我已经尝试过启用在grep . /sys/bus/usb/devices/*/power/wakeup中找到的所有设备的唤醒(如这里解释的@帕夫洛斯·西奥多罗的问题)，并发现这对于最近挂起的设备是有效的，但是如果我按下开关上的按钮将其更改为另一个设备，则挂起的设备将被唤醒。有没有人有过这方面的经验与USB交换机？

我也有过类似的问题。您应该能够直接启用键盘而不启用KVM。您还必须启用它所连接的usb端口。例如/etc/udev/规则。
# 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"这样做的原因是因为第一条规则自动启用了附加到它的所有东西。
