I can't help with this, but there have been issues discussed on the list with
different versions of Alva's firmware. Which version are you running?

Also, does the keyboard appear as a human input device to the USB interface?
If so, then it really should work, since this is supported at the operating
system level rather than by BRLTTY. I suppose you could make sure that BRLTTY
isn't intercepting the keyboard just to eliminate that variable from the
situation.
