Are you saying it is a hardware issue or are you hinting at a software issue on
GNU/Linux? I have used the embosser successfully from Windows over USB, so I
can confirm that the hardware works. Using ethernet is not an alternative, as
we have extremely restricted networking policies, with multiple layers of

Ok, upgrading liblouis works, although I'm getting a few warnings now.
Unrelated though, the output looks strange to me:

6-dot braille should not have dot 7 around ("hello") and the page number "#A" should rather be "#a". It might be a configuration/braille table issue. Just in case  you/anyone is aware of the cause. I'll look into it as soon as the embosser works :).
