I have a program which needs control of a mouse. I have a specific mouse attached for this, and I would like X to leave it alone. Unfortunately whatever mechanism in X autodetects and configures input devices, it is overriding any settings I make in Xorg.conf.
I know this because:
I have disabled "AutoEnableDevices" in Xorg.conf, and this stops it from interfering with my mouse. Unfortunately this is not a solution as it also stops it from correctly configuring my other mouse and keyboard, as a result buttons on both devices do not work correctly. (I know this is because my manual configuration of these devices in Xorg.conf is wrong, but I don't know how to fix it and can't find any helpful documentation.)
The second mouse has its own entry in Xorg.conf, along with /input/mice, and both have the driver set to void. Also, when I made a mistake configuring the first mouse it still worked when AutoEnableDevices was set.
How do I stop X using the second mouse?
(I have tried disabling the device using xinput, but it always ends up re-enabled after a minute or so. This may be because I am changing permissions so my program can access it without su privileges, but again I need to do that and would prefer a more stable solution than not touching it in the hope that udev forgets its there...)
