    2525 * The second device is the virtual USB mouse.  This can provide all the information that the PS/2 mouse can, and in addition, if the guest operating system understands this, it can provide the exact position of the mouse pointer.  If the guest uses this information then the position of the mouse pointer in the guest window should always match the position of the host pointer.  If the guest mis-understands this information there is likely to be a systematic difference between the two positions.  Currently there is no way of getting as much information about information flowing through this device as there is for the PS/2 mouse.

    27  * The third device of interest is the !VirtualBox "guest" device which provides a number of services for integrating applications in a virtual machine with the desktop and services of the host machine running !VirtualBox.  We are interested in its "mouse integration" function which sends the position of the host mouse pointer to the guest.  The guest operating system needs a special driver for the guest device, which usually comes with !VirtualBox, to get this information.  The guest device does not provide information about mouse button clicks - this is still sent to one of the other devices.  You can take a look at information flowing through this device - which includes guest requests for mouse pointer information - by setting the environment variable "VBOX_RELEASE_LOG=+e.l.f".
