Well, then the alternative is to let both drivers to handle this USB ID,
and add a code there on each of them that will check if the device is the
right one, perhaps by looking at iProduct string. If the driver doesn't
recognize it, it should return -ENODEV at .probe() time. The USB core will
call the second driver.
