Thanks.

Did you also try -b 57600? The baud could well be the issue, but that's what the fs driver is specifying.

Are you okay with building your own brltty for testing? If so, you might try changing line 651 of Drivers/Braille/FreedomScientific/braille.c:

from: .baud = 57600
to:   .baud = 9600

Yes, I agree, and am also curious.

Yes, exactly. You could also add serial (so both usb and serial), actually, in order to capture the configuration of the internal USB to serial adapter.
