Mulitple Mouse Buttons in MAX

Hi,
I'm trying to make the software end of a MIDI controller, mocking it up using a 3 button mouse as an input (via USB). ANy ideas as to how to seperate the 3 buttons into individual triggers? Mousestate is triggered by all of them.
I was thinking along the lines of finding out what data pressing a mouse button actually creates, I've seen this done using a piece fo software that i forgt the name of, but it showed the messages created by a USB game controller when buttons were pressed/ depressed (anyone know its name?!!?). Then taking this data and putting it into max somehow, again, any ideas how to do this? - ie. get max to read different data from a usb device and interpret them?

Sorry for all the questions, am very new to MAX, and am coming to the end of a BSc Music Tech, any help would be MUCH appreciated.

Thanks,
I'm on MSN at r.a.n.d.o.m.d.u.g.@h.o.t.m.a.i.l..c.o.m. (except without the dots obviously)
