Greetings.

Just wanted to update that i have resolved my problem.

I am able to interface with LS2208 scanner using python with the help of following python package libraries.

1. PyUSB - https://pypi.org/project/pyusb/

2. LibUSB - https://pypi.org/project/libusb/

After installing them, here are some additional resources that need to be install in order to avoid errors when the script is run. I found all these by googling so you can also find them .

To resolve No Backend Error

        -- Download the latest Windows binary:  https://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.21/libusb-1.0.21.7z/download

        -- Unzip using 7zip into a temp dir

        -- If on 64-bit Windows, copy MS64\dll\libusb-1.0.dll into C:\windows\system32. If on 32-bit windows, copy MS32\dll\libusb-1.0.dll    into C:\windows\SysWOW64.

Here is the python script i used to interface with the barcode scanner.

Change Log:

    -- Initial Release 02/17/2023

Description:

    -- Script to read barcode data from LS2208 scanner

    -- Script uses libusb and pyusb libraries

    -- Vendor ID and Product ID are mandatory fields

Steps to configure the script:

    -- Get Procduct ID and Vendor ID

        -- Go to Device Manager

        -- Select the correct device under Human Interface Devices

    -- Install the python libraries

        -- https://pypi.org/project/pyusb/

        -- https://pypi.org/project/libusb/

    -- To resolve No Backend Error

        -- Download the latest Windows binary:  https://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.21/libusb-1.0.21.7z/download

The read functionality is already present in PyUSB GitHub page. Just follow that and make sure you are trimming your non-printable characters out.

is your LS2208 mfd after December 2014 ?

This code works for Li2208, Here is a version that also read bar codes not only check connections
