No Braille after Debian 13 fresh installation

Hello,

I'm blind and currently struggling with a fresh Debian install with this 
image 
<https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-13.2.0-amd64-DVD-1.iso>. 
I installed BRLTTY with apt after the installation process (orca was 
installed without BRLTTY).

But my b.note display displays absolutely nothing, since it is in the 
supported list.

I tried booting BRLTTY with

sudo brltty

sudo brltty -b bn

sudo brltty -b bn -d XXXX:XXXX

sudo brltty -b bn -d usb:vendorIdentifier=XXX+productIdentifier=XXX

with informations returned by lsusb

My b.note is listed in lsusb, but maybe it's only detecting the keyboard 
because the braille b.note's keyboard is working.

I don't get errors, just orca saying the BRLTTY version.

I don't know what I can do next to solve my issue. I can't test other 
connexion way, my b.note is only using usbc, no Bluetooth.

Thank for help and your great work, and I wish you a good year.
