I just upgraded to brltty 5.4 from the ppa and am still seeing problems.
The system does not want to recognize my usb-to-serial and there is more
than one copy of brltty running.
Results of "ps -aux | grep brltty":

Hi all.
As some of you are experiencing problems with BrlTTY, I decided to go ahead
and backport 5.4 from yakkety to xenial. As per usual, these packages are
available from the Ubuntu Accessibility dev PPA,
https://launchpad.net/~accessibility-dev/+archive/ppa. BrlTTy will be built
and available shortly.
