This section describes the advanced settings in btnx-config.
This enables hot-plugging for btnx. This means, that when you plug in your mouse while your system is running, btnx starts automatically. This is done by an udev rule. It also starts btnx automatically when you wake up the system from standby. It is recommended that laptop users use this option because btnx quits everytime you put your computer to standby or unplug the mouse.
This adds the WAIT_FOR_SYSFS option to the udev rule generated by the Enable hot-plugging setting. Try it if you have trouble with hot-plugging. However, it usually creates more problems than it solves.
