[orca-list] problem starting brltty

[Michael Weaver <weavermicha googlemail com>]

I have just got my USB to Serial adaptor for my Braillenote M-Power but
I can't seem to be able to start BRLTTY.
as soon as Ubuntu Loaded and I logged in, I went to gnome terminal and
typed sudo brltty /dev/ttyUSB0 and after hitting enter I got an option
not found error message.
I even tried to replace the /dev with /d with the same results.
I am wondering if I need to add something like bn somewhere in my
command.
Hope someone can advise me.
