Whatever is hidden behind a /dev/cua*. ;-)  I suppose it's CDC.

AVRDUDE simply doesn't want to know that.  Those programmers where
AVRDUDE accepts a -P usb option are programmers where AVRDUDE talks
directly to using an application-specific protocol.  For all other
programmers, the parameter to -P must be a device node under /dev.
