Rev and USB?

[Graham Samuel]

Can anyone give advice about how to go about making a Rev-developed  
app talk to a USB interface? I'm thinking of writing something that  
talks to a GPS device which has no Mac software available from the  
manufacturer, but which can be linked to a PC via a USB cable. I am  
out of touch with this kind of thing and can't easily work out how  
hard it would be.

TIA

Graham
