Yay, progress!
I'm closing this as fixed since the problem is clearly much reduced, and
I'm opening a new bug 83939 for the two issues you mentioned.
** Changed in: linux-source-2.6.20 (Ubuntu)

USB braille display no longer starts with brltty
Thanks. OK passing it over to the kernel team. It seems the kernel
disables the USB device just after brltty tries to use it. See the last
line in the log clipping below:
Feb 1 10:50:00 laptop brltty[5861]: starting.
Feb 1 10:50:00 laptop brltty[5861]: BRLTTY 3.7.2
Feb 1 10:50:00 laptop
Oops, wrong kernel version. Sorry.

Also, try booting to a 2.6.17 edgy kernel with feisty userspace and see
if that fixes it.

Can you unload the ehci_hcd driver and see if this helps?
It looks like brltty is causing some USB resets, or is resetting the
device...I'm not sure this is a kernel bug, because it may be brltty
doing something wrong to cause these resets.

If you can give me more detailed information on what you are asking I
can give this a try. Note that the same braille display and the same
version of brltty work just fine on an edgy system.

Run:
sudo modprobe ehci_hcd
After that, see if restarting brltty works.
Also, please see about install linux-image-2.6.17-10-generic from edgy,
and booting that on the feisty system. I understand that the version is
the same on edgy, so it's unlikely to fix the problem, but there's
always the
The sudo modprobe ehci_hcd made no difference. When I tried to restart
brltty I got the same result. I also just tried the latest brltty sources from
head with the same result.
If it would help, perhaps I could allow you to ssh into a machine that exhibits
the problem. I'm normally not into

My mistake, use sudo modprobe -r ehci_hcd
Sadly nothing has changed.

An interesting new development here. Within the past half hour a new version
of brltty was uploaded and added to udev to support the auto detection of
braille displays on boot up. Braille now starts successfully for me. A couple
small problems remain though:
1. brltty attempted to start
Hi Mike,
ubuntu-desktop is just a meta package that causes other packages to be
installed/removed. You can safely remove it for the purposes of testing
whether this works. It won't remove the entire ubuntu desktop as such.
However for the long term it will cause issues with upgading, so it
should
Hi Henrik, removing the network manager and rebooting made no difference
with this problem.

Hi Henrik,
Thanks Mike. Hm, interesting looks like it's interfering with
Network Manager somehow. -- A new feature in Feisty.
I'll add a bug task for NM so the maintainers of that will
have a look.
In the meantime, Mike: could you try uninstalling
network-manager and see if that helps?
Mike, a copy of /var/log/syslog from when this happens might be useful.

Here is the requested syslog. Note that I killed the brltty process
after it attempted to initialize several times.
