I recently purchased an "Open USB IO Board" for experimental work.
The software for it can be run using a Live DVD which came with the
purchase or directly from within Ubuntu, the latter being preferable I
think because it saves me boot switching. Below is an extract from the
Quick Start instruction from the reference manual:

Open USB-IO Board: Extract from "Quick Start"
• Go to and download the appropriate ousb
binary. If the Live-DVD of development tools is being used then the ousb
binary and much more is already installed. For Windows select ousb.exe
file and place it in a convenient directory, ideally in the path. For
Linux obtain the ousb binary and place it in /usr/local/bin, you may
need root permissions to achieve this. If you cannot be root, then use
any convenient directory, ensuring the file has execute privileges set.
• Open a terminal and try running the program with no parameters to see
help information. Under Windows select Start->Run, type cmd in the text
box then hit enter. If the ousb.exe program is not in the current path
then use the cd command to move to the directory that contains ousb.exe.
Under Linux start a terminal and type ousb. If the binary was not placed
in the path again use cd to move to the right directory and type ./ousb
then enter.
If ousb under Linux gives an error message about missing libraries then
go back to the web site and obtain ousb_static (much larger but includes
the libraries) and try again. Some Linux distributions protect USB
access and so try using a root terminal.

I tried putting ousb.exe in /usr/local/bin (an empty folder) but was
denied because this need Permission. Of course I can use an accessible
"convenient directory" as mentioned above. However I am curious to know
about Permisssions. Please advise.
