I noticed this on one of my amateur radio reflectors. Perhaps this
might help someone.

Ubuntu 11.10, USB devices, and brltty

I recently upgraded one of my Dell Linux netbooks from Ubuntu
11.04 to
11.10. Much to my dismay I was not able to control my Icom
IC-7200 using
the USB port.
After many emails to W1HKJ in which I made false accusations
about a bug in
Fldigi, I did some further research and found the following
confirmed Ubuntu
bug:
https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/874181
As near as I can tell from reading this bug, a Braille utility
named brltty
is grabbing the USB port and not allowing other applications to
use the
port. The proposed solution is to remove brltty. I did this and
I can now
control my IC-7200 again via USB.
I suspect others having problems with USB control will have the
same issue.
So if you can't use your USB and you see a message in your
kernel log about
brltty attaching to your USB port, try removing brltty (unless
of course
you're blind and are actually using brltty).
I think the default Ubuntu configuration should be to not run
brltty. I'm
all for accessibility in computing, but to quote Mr Spock, "The
needs of
the many outweigh the needs of the few."
