Hello,
I try to run an Alva BC640 with BRLTTY 4.0 on Debian Lenny, and BRLTTY
can't start it. It seems that the Alva braille display is seen as a
USB stick. On this Alva I do not see how to switch in braille display
or USB stick.
In the connection preference of Alva, I specified USB-BT.
I start BRLTTY with
- braille-driver al
- braille-device usb:
Here is the part of the /var/log/kern.log concerning this connection:
