I have two braille dispplays Braillex Trio of Papenmeier.
With nvda 2020, the braille integrated keyboard of the trio doesn't works. Only the keyborard; the braille output works very fine. Even the commands I defined myself works.
In the nvda's log in debbug level, the entries with the braille keyboard are not related.
Do you know if someone in the dev team of nvda work on this problem?
