It's the Debian package, in which autogen and configure are always run
first.

What I find extremely odd here is this:

> #0  0x00007ffff7074848 in generalOperations3 () at target:/usr/lib/brltty/libbrlttybht.so
> #1  0x00007ffff7070788 in initializeSession (brl=brl at entry=0x555555650440 <brl>) at ../../../../Drivers/Braille/HandyTech/braille.c:1261

0x00007ffff7074848 is indeed exactly the address of generalOperations3,
i.e. not actually code, so it's almost questionable whether
gioGetApplicationData did properly return the address stored by
setUsbConnectionProperties.

That would be ideal, yes.
