What change to the functionality do you want to make? If you just want to grab the data as arbitrary input rather than "mouse" movement you can tell the driver to ignore this device, use the driver code as a reference for how to read it, and do this in userspace. Or you can probably tell the system to ignore that mouse and claim it yourself. It's unlikely you actually need to "reverse engineer" the dongle since it's functionality should be as standardly expected.Dalrymple
@ChrisStratton, yes, i need just mouse movements. Could you please send some references regarding "use the driver code as reference for how to read, and do this in userspace". All of these are related "writing drivers", right?Lemkul
"you need mouse just movements" ? Which is it - you need the movements present as a mouse, or you need them presented not as a mouse? Whichever path you take, you will have to do your own research and programming, but take time to study the existing driver if you end up needing to duplicate it.Dalrymple
I need to convert mouse movements to measure distance. Here is the sensor I want to build chest strap sensor:link. Then plot those data with matplotlib:linkLemkul

I had success reading my mouse with this code: orangecoat
