It turned out that the package in question isn't related at all to
the BRLTTY crash problem. Instead, BRLTTY crashes if I connect the Active
Braille to the USB port on the rpi and then starts BRLTTY.

However, BRLTTY works with a bluetooth conneciton to the device. But
sometimes the bluetooth doesn't work anymore until I reinit the
bluetooth conneciton by repairing the device. I don't konw why this
happens.

If the USB conneciton problem could be fixed, I'd happily provide log
information. Please tell me what you need and how to get the needed
information.

Thanks and regards,
