This is an input timeout, which is an expected error that wouldn't cause the 
driver to fail. It simply means that no key has been pressed, i.e. that there's 
no data to read from the device.

>The Braille display alternates between the messages 'brltty 4.1' and 'screen

About how long does each message stay on the display?

Would you be able to create a full debug log for brltty and send it to us (an 
attachment is fine)? You can do this by specifying the options -ldebug (to log 
as much as possible) and -e (to have the logs written to standard error), and 
by using 2> to redirect standard error to a known file.

This is known to work. Perhaps, though, the large size of the display is 
causing output operations to take long enough that they're getting close to the 
USB timeout limits. Are you perhaps using an extra long USB calbe and/or hubs?

>and our /etc/brltty.conf is setup as follows:

>braille-device usb:
>braille driver fs

Could you please attach your brltty.conf file just so that we can have a direct 
look at it?

>We performed the install as follows:
>
>./configure -with-braille-driver=fs

It's probably a typo here, but there should be two minus signs before the with. 
For example: --with-braille-driver=fs

Note, though, that you don't really need this option. If you don't specify it 
then all the drivers are built as dynamically loadable objects.
