Hi, I tried lots of things, like recompiling Brltty from Arch build system, downgrading Brltty and ICU etc... Nothing helps. The strangest thing is, that when I just start Brltty and let Orca running, Brltty accepts braille write requests but it doesn't output anything on the display. However, display is correctly identified as a Freedom scientific display. Still no suggestions? thanks, Vojta Dne 22.4.2014 12:52, Vojtěch Polášek napsal(a): > Hi, > Okay, I have made some progress.
