Grmbl. This is yet another case of
https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/153662
https://bugs.launchpad.net/ubuntu/+source/hal/+bug/175182
and similar. Yes, the "fix" is to remove brltty. As I explained in
153662, it's hard for blind people do debug why their braille device
doesn't work since it's that precise braille device which allows them to
access the machine...

Luke, you need to comment that entry from the udev rules file too.

BTW, I see that you have commented the 0401:6001 entry from the udeb
version of the udev rules too. I don't think it's really necessary:
will really people use a usb-to-serial converter to install Ubuntu
nowadays? While people using Seika or some HandyTech devices do need to
install Ubuntu with them.
