When the Focus Blue is unplugged I have the following message in
the log every second:<br>

I meant the user was able to use the Focus Blue on his computer
on Debian 10.<br>
<br>

<pre class="moz-quote-pre" wrap="">Also, is the user actually using the device?</pre>

The user uses both speech and Braille with Orca, yes, but it
seems he relies primarily on speech.<br>

<pre class="moz-quote-pre" wrap="">Which log level? There are more log levels involved here. What the

I meant BRLTTY log level.<br>

<pre class="moz-quote-pre" wrap="">Again, was the user actually using the device? If it was properly
functioning, I wonder why BRLTTY was apparently retrying to initialize</pre>
</blockquote>
I confirm, BRLTTY seems to disconnect/reconnect to the device,
the user see the message BRLTTY 6.1 then it works again. It is
quite similar of what I see on my Seika device when it is
plugged to the computer.<br>
<br>
<blockquote type="cite" cite="mid:87sg8y676q.fsf@blind.guru">
<pre class="moz-quote-pre" wrap="">the device again and again. Could it be that more then just one BRLTTY
were trying to fight over the same device? IOW, did you check that only
one instance of BRLTTY was running?</pre>
</blockquote>
A "ps aux |grep -i brltty" gives me only one instance of BRLTTY
running.<br>
<br>
Restarting the computer with the Braille display plugged makes
it working and after some times of usage the issue occur again.<br>
<br>
Just new log I found (I give you not only BRLTTY log because I
don't really understand them and I would like to provide you the
most informations as possible):<br>
