Have a look at the RawInputSharp library from this page. It uses pInvokes into User32.dll to get hold of input device information. Using it you can detect which device (ie. mouse) input is coming from.

The tricky thing would be to identify which device id is that of your touchpad automatically, but you could manually configure this in your application.
