Because some device manufacturers don't obtain unique vendor/product ids for
their products and thus BRLTTY can't distinguish between genuine braille
devices and certain other hardware.
The solution is simple: if you don't have a braille display then make sure
that BRLTTY is not installed. Those who do have a braille display really need
it for accessing their systems.
Dependency resolution shouldn't result in installation of BRLTTY for users who
don't request it, though. Would it be possible to find and fix those
dependencies?
