[BRLTTY] BRLTTY with Alva BC640

[Dominique Asselineau]

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:
