I'm trying to run virtual mouse driver from book "Essential Linux Device Drivers" but when I load this module into kernel using insmod in /var/log/Xorg.0.log I see:

[   757.212] (II) config/udev: Adding input device  (/dev/input/event10)
[   757.212] (II) No identifier specified, ignoring this device.
How can I force Xorg to don't ignoring this device, or what I must add to kernel module code to specific identifier for this event?
