蓝牙设备Logitech的udev规则

Question

我想为Logitec蓝牙编写udev规则。我的键盘和鼠标连接到PC作为一个蓝牙设备。

当我监视udev时，我看到键盘和鼠标都有单独的事件。我想让鼠标使用，但不允许键盘。如果我忽略了这个设备，我就不能使用鼠标。我怎样才能做到这一点？我可以忽略键盘事件吗？

Answer 1

到目前为止，对我起作用的只是找到文件/lib/udev/rules.d/97-hid2hci.rules。

找到这个条目，并将其注释掉：

    # Logitech devices
    KERNEL=="hiddev*", ATTRS{idVendor}=="046d",
    ATTRS{idProduct}=="c70[345abce]|c71[3bc]", \
    RUN+="hid2hci --method=logitech-hid --devpath=%p"

应该是这样的。

    # Logitech devices
    #KERNEL=="hiddev*", ATTRS{idVendor}=="046d", 
    ATTRS{idProduct}=="c70[345abce]|c71[3bc]", \
    #  RUN+="hid2hci --method=logitech-hid --devpath=%p

保存文件，拔出插头，并回复接收器，它可以正常工作。

我看到的唯一问题是，这可能会被覆盖在更新中。我还没有找到更好的解决办法。
