How to create/simulate multiple mouse devices (in dev manager) in windows 8.1 and above?

Question

Is their any way to install/enable multiple mouse devices in windows 8.1 and above and simulate input to them? I would write a driver if their is no other way. If I need to write a device driver does anyone have any good pointer tutorials that would
get me started?
I found this for communicating with an already installed device which is hooked up to the computer.

I wonder if installing something that's already in the driver store using DiInstallDriver and enabling it (possibly via CM_Enable_DevNode) would work?
My goal was to create/install 4 mouse devices and communicate with them via the windows.devices.humaninterfacedevice library. Would this be possible?

Answer 1

you need to write your own driver. you will need to write a HID miniport. from that one miniport you can describe as many HIDs as you want. you can write the HID miniport driver in UMDF if you want to stay in user mode.
the namespace you link to above will not create HIDs and the normal rules about not allowing you to open a keyboard or mouse HID from user mode still applies.

That almost an answer. I was wondering if this is good example of what you were talking about:

If so, does that mean I need to use direct calls to HID.dll or other libraries in order to read from the custom mouse device? I have seen many implementations of filters which end up poorly (maybe not everyone but the multiple device ones mostly) and
I am not for sure about the miniport drivers.
