Dear Group,

I have got two mice connected to one PC (notebook).
In example I click parallel left button on mouse A and left button on
mouse B. Is it possible, programmatically detect which on which mouse
which button has been clicked?

Mainly, the thing what I'm doing is to connect to 'scroll button
click' a Halls sensor (contactron), one for each mouse, and I need to
count down the sensor signals. The simplest way is to fetch the mouse
events with C#, but what would happen in case of two mice?

Those mice are connected via USB port - no way to do it via RS232
port. Shall I detect a hardware on USB port and then read data from
it? In fact I'm interested in reading signal from exactly one button
for each of mice's. I cannot define that one sensor is left button and
another sensor is right button, because the third mouse (notebook
touchpad) is used normally, so I cannot bind 'common-use buttons'. Any
ideas?

Thank you for all answers!

All the best,
