and should I also change the configurations in /etc/brltty.conf to make it 
work, right?
or does the binary do everything itself, I mean, it has already saved the 
options I gave it while configuring?

PS someone told me to generate a .deb package and dpkg -i brltty.deb
but I do not know how to do this...
I am afraid that with apt-get update && apt-get upgrade, then, it 
reinstalls the 3.4.1 branch and farewell to USB!
