the devise works fine, but the example don't work,

I copied the same code and I changed productId and vendor.

I think, this condition is no more applicable: the end of stream is not a '40'

 if (chunk[2] !== 40) {
                        bcodeBuffer.push(this.hidMap[chunk[2]]);
                    } else {
                        barcode = bcodeBuffer.join("");
                        bcodeBuffer = [];

                        this.emitDataScanned(barcode);
                    }

UPDATE : I added an "ENTER" suffix to the barecode scanner, but some characters are not supported by the library, I thinks hideMap doesn't cover all character
