BTW, the fact that data from a device is available from /dev/input/mice does not mean that device was recognized as a mouse, a touchpad or something else. It just means that kernel is able to approximate device as a standard PS/2 Expolorer mouse. > it still provides a reasonable user experience until the user has installed our > guest drivers. It is your call but I would much rather if you worked on fixeng evdev to work with your virtual device rather than having to install a new X driver and going through the hoops trying to detect which one should be used on a particular box. At least on Linux...
