我连接了鼠标bluetoothctl
sudo systemctl enable bluetooth.service
sudo systemctl start bluetooth.service
bluetoothctl
> power on
> default-agent
> scan on
> pair C0:56:C2:25:49:AE
> trust C0:56:C2:25:49:AE
> connect C0:56:C2:25:49:AE
> quit
鼠标已连接并正常工作，但是如果 2-3 秒不移动鼠标，它就会断开连接。
我已经创建了/etc/bluetooth/input.conf：
[General]
IdleTimeout=0
UserspaceHID=true
还向 udev 添加了一些规则/etc/udev/rules.d/91-local.rules：
ACTION=="add", SUBSYSTEM=="bluetooth", ATTR{product}=="Razer Atheris", ATTR{power/control}="on"
我bluetoothctl可以看到它“创建”了一个新设备，然后2秒不动（它不打印任何东西），然后我移动鼠标，它开始打印[DEL]（我必须一直移动鼠标），然后它开始打印[NEW]（句柄十六进制数也是新的），然后打印[CHG] Device C0:56:C2:25:49:AE Paired: yes（我仍然必须移动鼠标），然后光标移动。

答案1
好的，通过结合更多来源，我找到了答案：
首先找到、配对并连接鼠标：
sudo systemctl enable bluetooth.service
sudo systemctl start bluetooth.service
bluetoothctl
> power on
> default-agent
> scan on
> pair C0:56:C2:25:49:AE
> trust C0:56:C2:25:49:AE
> connect C0:56:C2:25:49:AE
> quit
然后在 中找到idVendorand （在 less 中使用 find ）idProductsudo lsusb -v | less/Procuct_name
然后在以下位置创建一个文件/etc/udev/rules.d/50-usb_power_save.rules：
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="<Your_Vendor_id>", ATTR{idProduct}=="<Your_Product_id>", ATTR{power/control}="on"
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="<Your_Vendor_id>", ATTR{idProduct}=="<Your_Product_id>", TEST=="power/autosuspend" ATTR{power/autosuspend}="0"
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="<Your_Vendor_id>", ATTR{idProduct}=="<Your_Product_id>", TEST=="power/autosuspend_delay_ms" ATTR{power/autosuspend_delay_ms}="0"
然后运行：
sudo udevadm control --reload
sudo systemctl daemon-reload
那么一切都会永远顺利:)
