Thanks Perry for your info, yes documentation is sadly not as good as the product, and often you are directed to subscription-based tutorials...

In my case however, it was just a port issue, I was not sure about this, but you just have to use a separate openerp-server.conf for the POSbox instance, and then configure the address *and* port of that instance in your odoo main server configuration, after that, everything worked out of the box!

You need to follow the POSbox setup guide to the point, though, and configure the udev rules exactly as shown - I had some other rules that were valid and perfect for udev, but did not work for POSbox, I guess the python code tries to access the udev devices over a different path/node.

Hi Gregor,

We have just been through this entire process, it took a week to figure out. Documentation is very poor. There are some vital elements that are omitted from the documentation.

The problems you face are mainly to do with permissions. The correct way to install the Odoo instance is under a user and not root(which I am assuming you have done). This is all good and well, however when you come to install the Pos portion as an add on the Python installation(which was installed under the user as part of the oodo instance) does not have the correct permissions to access the hardware. We also had the added issue of linking old scanners via serial ports and not usb, so to get that to work we added the user to a group named dialout which is already loaded. I am not 100% sure but I think this resolved the printer not connecting as well, we were busy with so many options at the time.

hope this helps :)
