I use an Alva BC640 and have the same lock up problems. It happens both
in the desktop and at the console (I work primarily at the console). The
only solution I have found is to shut down the display (power it off or
unplug it from the usb) and then reconnect. After that it works fine
again. However this tells me it is not a unity problem perse but some
thing in the underlying system be it a kernel issue or a brltty issue. I
have not done a full investigation nor reported it to the brltty fols yet
to see if they are experiencing it.

hi.
i am using ubuntu 14.04. i have found some problems in it.
first the dash doesn't work. this problem has been reported earlier from
others.
second i have some problems with braille. sometimes my braille display locks
for some reason. i can't use the buttons on the display to go 40 characters
forward. i use an baum supervario.
third i can't read the battery percent and time ramaining in braille, but it
is spoken. i mostly relay on braille som it would be good if it worked.
i don't know if i should report these bugs somewhere else or if it is enough
if i write here.
regards Oskar.
