<p>I doed a detailed test (unfortunatelly without success result) to
follow back what versions of BRLTTY worked right previous this old
Focus1 modell.</p>
<p>I downloaded Ubuntu 18.04.6 Eol supported release (this release
contains BRLTTY 5.5 revision).</p>
<p>When I used manual BRLTTY start, I used the -ldebug,usb
parameter, and use the -L option.</p>
<p>The log file with the right english language error message is
following:</p>
<p><a class="moz-txt-link-abbreviated" href="mailto:2024-04-11@09:11:18.207">2024-04-11@09:11:18.207</a> [brltty] USB URB status error 75: Value
too large for defined data type.<br>
</p>
<p>I see this error message too the BRLTTY 6.6 release in my Debian
Bookworm Mate release.</p>
<p><br>
</p>
<p>I attached the detailed log and sudo lsusb -v result.</p>
<p><br>
</p>
<p>Me need trying older releases to detect when worked right this
old modell with BRLTTY? What version you suggesting if this is the
case, or how possible we forwarding the right direction to I have
possibility to use this old display with 64 bit architecture in
Linux with newer systems?</p>
<p>Need a more detailed log? If yes, what options I use when
generating the log file in BRLTTY?<br>
</p>
<p>I am absolute sure newer Focus modells works right with BRLTTY
(if it wasn't like that, other Focus display users on this list
absolute sure would have already reported it, the strange thing is
that I didn't even see a similar error report regarding Freedom
displays). Maybe I'm the only one who wants to use an old display
as a solution (now me not have better possibility).<br>
</p>
<p>Does it make sense to open a bug report on the Github bug tracker
for this error message?<br>
I want to avoid an unnecessary error report if it is an error that
cannot be fixed, that's why I'm asking.<br>

<p>Hi List,</p>
<p><br>
</p>
<p>I get a very old, but working Focus 1 Braille display (70 cell
modell), but I am unable to yet request to working with Linux in
console and Orca in Brltty. :-):-)</p>
<p>Perhaps have a fatal thing with I am not known yet this display
type (I newer worked with Freedom Scientific Focus modells).
:-):-)<br>
</p>
<p>I connect the display with a normal USB cable the right hand
USB connection, my braille display I seeing the focus 70 text in
Braille, more space character, perhaps a dot 5 point, a 46 dot
combination, and a 356 and 12 characters.</p>
<p>Lsusb says following this display:</p>
<p>Bus 001 Device 008: ID 0f4e:0100 Freedom Scientific <br>
</p>
<p>Enjoy, not more. :-):-)</p>
<p><br>
</p>
<p>I have got an Alva Satellite 570 pro modell with works
succesfull with Brltty, during I looking the focus display I
turned off my Alwa display and restart brltty.</p>
<p><br>
</p>
<p>Because I newer seeed Focus Braille display, what can I need
doing to Debian 12.0 and Ubuntu 20.04 BRLTTY works perfect the
Focus display?</p>
<p>Because Braille displays are very expensive in Hungary (larger
cell modells are more than 800 thousand ft), I would save the
Focus Braille display as a backup device later in case my old
Alva Satellite 570 display breaks down, but I would like to know
for sure how to get this model up and running under Linux later.
:-):-)<br>
Unfortunately, the Perkins Braille keys stick during use, but
you can read perfectly on this model as well.<br>
</p>
<p>Is this model still serviced at all in the European Union or in
the United States? Can you get parts for it?<br>
Actually, only the keyboard part should be renovated, the cells
are intact, although I could give a complete assessment of the
state of the piezo cells if the display was working in Linux.<br>
</p>
<p><br>
</p>
<p>The display is a Freedom Scientific Focus1 70 cell display.<br>
I attached a log using the sudo brltty -ldebug -L brltty.log
command, compressed in zip format.<br>
I see this interesting part the log file (I am using in Ubuntu
20.04 with Brltty 6.5 with Linux 5.15.0-101-generic kernel):</p>
