I think it's that.

No hurry :-), I'm in a place where bandwidth is very small ; I 'll be in Paris
in two weeks and their, I'll have a good bandwidth.

yes ; just three lines :

braille-driver	pm	# my driver is a Papenmeier
braille-device	usb:		# First USB device matching braille driver
text-table	fr_FR	# French (France)

Yes, but no idea about this basic configuration.

1. ftp://ftp.osuosl.org/pub/lfs-livecd/lfslivecd-x86-6.3-r2130.iso

   This one is old but it was explain how to customize the iso so that is
   boots without doing nothing and have is own configuration. Overwise, the
   user has to type a boot command after the beep ; this command is of the
   form :
   linux brltty=code_of_the_braille_driver,devie,code_of_the_braille
   This must be done using an english keymap (the default but it is not so hard).

2. http://download.grml.org/grml64-full_2014.03.iso

   If I remember correctly, after the beep of the boot, the command to give
   is sothing like :
   grml brltty=code_of_the_braille_driver,devie,code_of_the_braille

   As for the LFS, it is explain how to customize the ISO for a USB stick

3. http://cdimage.debian.org/cdimage/release/current/amd64/iso-cd/debian-7.7.0-amd64-netinst.iso

   For this one, I don't know if it is customable and the command after the
   beep is simply
   
   brltty=code_of_the_braille_driver,devie,code_of_the_braille

I hope thisis really correct because I didn't instal a distro recently.

Bright :-) I'll enjoy testing this script.

Nice. I had some doubt about this.

Many thanks.
