Hello,
On a text console does your braille display
work?
Have you enabled brltty systemd service to
start brltty?
If you are unsure you can just do
sudo systemctl reenable brltty
sudo systemctl restart brltty
At the orca side of things braille support is enabled
by default. Have you enabled it? Please open screen
reader preferences by pressing orca+space, switch to
the braille tab and please verify if evething is
correct.
If you can't get it to work, then please try to describe
what works, what does not, when it stopped working and
similar things that may help us look for the issue.
Also can you see some errors when checking brltty status
