_constraints = [(_check_ean_key, 'You provided an invalid "EAN13 Barcode" reference.

The problem is not only disabling the EAN13 validation in OpenERP but also the scanner.
The EAN13 validation method is a way of decoding a barcode. Because the barcode itself is not correctly formatted it will not scan.
Maybe you can use a different barcode configuration in the barcode scanner (e.g. code 39)
If the barcode produce the same output as you do, when you manually entered the information it should work.

There is a function check_ean in devices.js in point_of_sale/static/src/js folder. Try customizing it and related functions.
