Yes I know this issue. To fix it, add the following line to your brltty
configuration file:

braille-parameters eu:protocol=iris

The prblem is that protocol audtodetection seems to be broken somehow.
Until it is fixed, it won't hurt to specify the protocl explicitly so
that the driver will at least be called.
