Hi Alan,
I don't think, that it was the RPi - because now it even works on the
RPi. Furthermore I had the problems before RPi with Ubuntu 12.04 on the
same desktop machine I used to run with 10.04.
In order words, the device now works with the same computer and OS that
it used to fail with befo

with the new trace.
Now I have a trace from my Ubuntu 10.04 system

begin of the problems, it's 3.2.+ - included in Debian wheezy and Ubuntu
12.04.
Up to kernel 2.6. it is currently working correct.

Hello everybody,
I am trying to get a USB IO Board running with Debian on Raspberry PI

The board used to run fine with kernel 2.4.+ (e.g. Ubuntu 10.04) - a
