Read a mouse with an Arduino ?

Hi everyone
I've got a project where I'd need to read my mouse's signal. My mouse is a G700S (so USB) and the thing was I don't really know how to do and even if it's feasible.
I'm using an Arduino Micro and my initial idea was to get a PS/2 to USB Adapter (I already have one) and then to plug it to something like this wired to my Arduino.
So my question basically is "will it work ? and if not, why ?"
Thank you in advance

Will it work? No
Why not? Because you need a USB host not a USB client which is what the Arduino is.

It might work if you get a USB host shield but you will then need to get a Mouse driver software for this.

But why does this work then ?
Because as I explained to you, what I want to do is use this adapter in order not to have USB but PS/2. And this page seems to say like it would work...

Hi,
Do you have a USB to PS2 adapter?(Big difference)

The PS2 keyboard interface is not USB and using a Library can communicate with the arduino.

As explained works as PS2 to arduino, they then say you can use your USB to PS2 adapter.

GrumpyMike is correct. USB host is not possible with the arduino.
But using this will possibly make it possible.

Tom.... :slight_smile:

Yes effectively I expressed myself wrongly in my first post I was talking of the USB to PS2 (this one), sorry.
Though, I read somewhere that only some mice (and the old ones in most of the cases) would work with the adapter. Is there any other way to get their data then ? I think not but I just want to be sure.
