It depends. If the device uses the built-in USB Audio Class driver,
you should see both instances of the device show up on the system. The
built-in USB Audio Class driver supports multiple instances of the
same device just fine.
If the device uses a custom driver, then all bets are off. I would
hope that you would always see the first one you plugged in, but it
really depends on how the driver works. I imagine that if you booted a
machine with both plugged in, the one the system would see might be
random.
FWIW, there's nothing in the system that would keep a developer from
making a driver that supports accessing both devices simultaneously
when plugged in.

The maker of the device says they do not support multiple devices at
the same time.
What will actually happen if I connect two identical USB audio
devices to one Mac?
Will OS X name them differently?
