Then I'd say those are all the directories (separated by ':') that have been added to your $PATH and your component needs to be in one of those, I think.

Ok I found the folder, but I don't have permission to save there

Yes, those are system folders. So maybe try sudo in front of the terminal command. Or open an filemanager with elevated privileges like 'sudo nemo'

As I said, you will need to use sudo

sudo cp thefile /usr/bin/thefile

Ok, I solved this problem.

Now I need to import the pyusb library. How exactly do I do that?

Is it possible to develop a realtime component to do this?

An userspace component may not be fast enough for what I am trying to do.

I don't think that realtime has access to the USB port. (And USB itself is not realtime)

I am having a lot of trouble to install the libraries because of the Linux version I am using (10.04)

The website which it gathers the libraries from does not support Ubuntu 10.04 anymore.

Updating Linux version is not an option at the moment.

Any ideas?
