Isolating mouse data in DirecShow with multiple mice connected

[keeranj]

I'm trying to use directinput to allow me to set up two mouse devices one mouse device is used normally to control the cursor on screen and the other mouse is used to control movement on screen in my application.

Is it possible to isolate one mouse such that it doesnt affect the cursor movement but i can still access the mouse data using the normal mouse data structure?

Is it also possible that each mouse can also be recognized by the application (perhaps through a USB identifier) such that even if i disconnect and reconnect each device repeatedly the individual mice will remain to do their respective jobs.

Any help is greatly appreciated. Thank you
