Direct Devices | Odoo Point of Sale

What version Odoo is this video based on? I don't have Direct Devices. Instead I see ePos Printer. When I check the box it requests the printer's IP address. However I'm using a USB cable to connect as it wasn't working via ethernet. Is it possible to connect to Odoo via USB?
