Error with braille display

[Sérgio Neves]

Hi,
I have an HP pavillion laptop and a focus 40 braille display (usb interface).
I have ubuntu 7.04.
When I boot this ubuntu version from the cd or from the hard drive where it is installed, I think brltty sstarts up with ubuntu and I don't need to do nothing.
What happens is the following:
In the normal cenarius, brltty presents the message
brltty 3.7.2
then presents
screen not in text mode
because ubuntu starts with the graphical interface.. Then when orca starts, the braille display works too.
Sometimes, instead of presenting
screen not in text mode
it presents
1 startup error
and I cannot put orca working with the display.
When in this situation, I typed
dmesg > filename.txt
and the content from the beginning is:

[ 738.220000] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use

[ 738.260000] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use

[ 738.300000] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use

[ 738.340000] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use

[ 738.380000] usb 3-1: usbfs: process 3349 (brltty) did not claim interface 0 before use

... (it's the same thing till the end)

Although in this situation it doesn't work with orca, it works with the textual consoles.

What's the meaning of this? And what can I do to solve this?

I don't have experience.

Thanks for the attention

Best regards
