Je n'ai pas mis exactement ces options car je voulais exécuter un lsof
pour voir qui occupe le port usb, mais j'ai tout exécuté sous la
commande script.

La commande lançant BRLTTY, elle-même placée dans la commande ./esys,
est donc

# /usr/local/bin/brltty -b eu -d usb: -t fr-vs -l 7 -e 2>/root/esys.log

En pièces jointes, il y a 
 - le log de BRLTTY (esys.log), 
 - le résultat de la commande script (esys.script).
J'ai également mis 
 - une copie d'écran de ce qui se passe lorsque je branche l'ESYS en USB 
   (usb.log)
car il semble être vu comme un disque amovible...  Au passage, lorsque 
l'ESYS reste branché au redémarrage de la machine, ce redémarrage reste 
bloqué sans que je puisse voir réellement pourquoi car je n'ai pas la main 
à ce moment-là.

Le log de BRLTTY semble indiquer que le port USB est occupé alors
qu'une commande "lsof /dev/sdb" ne confirme pas.
