Since several weeks, I search to run BRLTTY with driver Baum.
Unfortunately, it seems that it doesn't work. Indeed, BRLTTY crashes
constantly when I using keyboard.
Are you aware that you have more than one brltty running at the same
time? If
you are, could you please explain what each one is to be doing so that
we can
better understand what's going on. If not, perhaps that's the source of
your
problem.
Thank you for your reply.
Hmm... Nevertheless, I don't have multiple instances of brltty. Anyway,
I don't see more than a brltty process together when this occurs.
Additional details:
- The problem doesn't occur with the BrlAPI. Eg. it works perfectly with
Orca. So, the problem occurs in TTY mode only.
- In the system logs, I have the next error regularly:
`kernel: usb 1-1: usbfs: cmd failed USBDEVFS_CONTROL brltty rqt 128 rq 6
len ret 255 -110`
Please see the attached file for more infos.
Thanks again,
André
