Hi,
I forward a message I sent to the NVDA list regarding braille support of
NVDA via brltty and an USB connection.
I've set up brltty and libusb-win32 according to the instructions given
by the NVDA team.
I use an Alva Satellite 544 connected via USB. When I start the brlapi
service, I get the message that it has been started successfully,
however I don't see the startup message of brltty.
When starting NVDA with braille, I get no error message but no braille too.
I created a debug file, which I've sent to the NVDA team. They advised
me to contact the brltty developers. So here I am.
Can you please check the file to see what eventually might go wrong?

Hi,
I don't know whether this list accepts attachments, but I'll try it.
I've created a protocol, that indicates some strange messages: See the
very first line and those that say "No drivers/devices found"; I
sumarized them.
However brlapi is reported as having started successfully.
