On Linux, occasionally, my Bluetooth stack forgets about the established pairing to my Braille Star. In that case, I can not even repair the device. I have to manually delete all state files in /var/lib/blueooth and let the bluetooth stack recreate them. This is very anoying. It has hit me at least two times. Once with Bluetooth 4, and once with Bluetooth 5. I am suspecting the Linux Bluetooth stack to be buggy in a subtle way. > If the USB conneciton problem could be fixed, I'd happily provide log > information.

If gdb comes back with a prompt, enter "bt" to see the backtrace and send that over. -- CYa, ⡍⠁⠗⠊⠕ _______________________________________________ This message was sent via the BRLTTY mailing list.
