I am confident that it's not possible to determine which mouse produced the input messages from usermode ring-3. However, it might be possible at ring-0... by implementing a mouse filter driver which connected to \\Device\\PointerClass0 and other pointerclass input devices on the chain. But I can only imagine the chaos when multiple pointer devices are moving at the same time. Sounds a bit difficult even at this level to me. But if you want to explore, the sample code in the Microsoft DDK at: C:\WINDDK\3790.1830\src\input\moufiltr could be modified to research this idea. Best Wishes, -Randor (David Delaune)
