[Ham-Mac] How to create a device driver???

[Bill Whitacre]

Man, if you figure out how to do a USB device driver, let us all  
know!  I'd love to see one for the PCR-1500!

We use Mac laptops and Drake R8s for a network of remote monitoring  
systems and I'm getting a little concerned that shortwave radio may  
outlast my supply of R8s!  ;-)
