Updating the linux kernel to Ubutu Breezy (2.6.12-7) partially solved the
problem. It is a painful process though. I spent quite sometime to update
the kernel image (to download all the dependent packages and fix the
problems). I am reluctant to build my own kernel. There are too many
Ubuntu (or Debian) specific patches and I still do not know how
to build my own kernel on Debian yet. So I have to use the
Breezy (testing version of Ubuntu) kernel. Then I need to update
libc and some other packages. I need to fix the problem of
libc6-devel conflict with some of my existing packages. I think
I need to try out the kernel building process on Debian again.
Back in the days of Slackware 3.5, it was a much easier process (even
though the computer was not as fast as my new AMD64 desktop).
Anyway now it works most of the time. I can now send and receive
from the board with CDC firmware. Right now only gtkterm
(gtkterm -p /dev/ttyACM0) works but not minicom and cutecom
(time out).
Hotplugging is still causing problems. To unplug and plug solves the
timeout problem sometimes. I would like to update the hotplug system
as well. But I run into dependency problem again. Right now I am
reluctant to update the whole system to Breezy ( I do not really
need that cutting edge stuff).

I think this is a kernel driver problem with my system (2.6.10
Ubuntu ). People have reported that it works with 2.4 kernel with
another Debian based system. To bad upgrade to a 2.6.11 universe
kernel locked up my computer. :(
I've tried Fedora Core 3 as well and the situation is
the same.
I've set the right permissions to the /dev/ttyACM0.
Any people here get it to work with a 2.6.x kernel?
