I'm trying to create a windows application that can manage multiple mouses, with the feature of understanding which device is generating the input (something like Microsoft's Multimouse, but without a UI).
The problem is that I don't want to use a UI because this will be a plug-in for Unity3D so I have many limitations imposed from this.
I also thought about a parallel service that can talk with Unity, but in that case I would like to not block all the system to take mouses inputs. In this special case I have to manage 12 of these devices: AimTrak, that are recognized as a mouse input device. So does anyone have some idea about that how can do this without hacking them and rewriting their driver?
