[BRLTTY] BRLTTY and Orca with Varioultra 40 braille display

[Jason White]

I just acquired a new Varioultra 40 display. It is the version from 
Visiobraille with the USB-C port.

It is working reliably with BRLTTY, answering the question discussed on 
the Orca list recently and on the BRLTTY list. This is why I am 
cross-posting my comment.

As usual, once BRLTTY gained control of the display, Orca worked with it 
immediately.

In case anyone else has this difficulty, I found out that it was 
possible for the display to charge via the USB port without the host 
system being able to detect it as a USB device. That is, it didn't 
appear in the output of the lsusb command. The cause turned out to be 
that, although the USB cable was tightly connected, it still wasn't 
fully attached. You have to press the connector in the right way to make 
sure it engages completely.
