The Diamex programmer uses a Virtual Serial Port, so you don't have
to use "-P usb" but rather "-P /dev/cu<whatever_it_is_named>".

I guess if you do a "ls -l /dev/cu*", it should be obvious which
device name your OSX gave it.  There probably aren't so many of
them around.

Using "-P usb" is only meant for those programmers that don't use
a Virtual Serial Port but are talked to directly through libusb
(like the original Atmel tools).
