BRLTTY does not start automaticaly.  However it runs manually as
noticed Sherab

# brltty -b hw -d usb:

On my professional machine, I am not root.  I am sudoer to start, stop
/etc/init.d/brltty and I can also configure brltty.conf.

In brltty.conf i forced
braille-driver hw
without success.

On Wheezy, it is BRLTTY 4.4.
