QUESTION
I'm trying to retrieve scanned data from barcode scanner in Node JS. I'm not sure whether this is correct question. Sorry if the question is wrong.
The barcode scanner model is Honeywell MS 9540. I don't have an idea how to implement it. Node JS found it as a USB device. Is there any way of implementing it?
I'm building an app for Windows in Electron and thinking about using local Node JS server for for retrieving data from devices.
I've used usb-barcode-scanner
package in Node JS. And it could find barcode scanner among other USB devices. But I'm getting an error:

QUESTION
I have a Honeywell N5600 that I'm trying to use, but I don't get it to scan anything.
The device is recognized as /dev/hidraw1, but as it does not have any button to press, I cannot trigger the scan and thus, when I try to read from it, it just waits forever.
I started creating a python program, that seems to be able to communicate with it (different return values):

You need a Windows PC that can connect to the Internet, but there is a tool called EZConfig-Scanning that configures and maintains the scanner.

Perhaps the recognition device /dev/hidraw1 is probably because the scanner is set to USB HID Bar Code Scanner mode.
If you change the setting to USB Keyboard(PC/Mac), it is always readable and the barcode you read will be notified as keyboard input.
By changing the setting to USB Serial, reading start/stop can be controlled by SerialPort command transmission. The barcode read is notified by receiving data from SerialPort.
