I made a Windows Form Application in order to be able to read barcodes, but when some multiple scanners are connected to the same PC and they scan something in the same time, the output values are mixed.
The idea is that every scanned barcode have to be added in an Excel file, but if the characters are mixed I cannot add the correct values. I use the KeyPress event of the form because it's a Keyboard Wedge Emulator.
The scanner is an LS2208 by Motorola Symbols. I understand that Microsoft Point of Service library won't work with this scanner model. Do you have any idea on this matter?
The LS2208 does not support Windows.Devices.PointOfService, but it does support OPOS.
And the fact that it supports OPOS can also be used with POS for.NET.
If you are developing your application in C# and are looking for a way other than the Keyboard Wedge Emulator, you can use these.
Windows.Devices.PointOfService: LS2208 unsupported
Supported Point of Service Peripherals
This mode is similar to connecting with a serial port.
SYMBOL LS2208 GENERAL PURPOSE BARCODE SCANNER SUPPORT
LS2208 Product Reference Guide (en)
Please refer Page 35 USB Device Type -> OPOS(IBM Hand-held with Full Disable)
OPOS:

POS for.NET:
POS for .NET v1.14.1 SDK Documentation
Microsoft Point of Service for .NET v1.14.1 (POS for.NET)
Or if you don't want to use the above library, you can connect with a serial port and control it directly.

I'm developing a windows application with using scanner Zebra MC33.
There is SDK pack which is described here: https://www.zebra.com/us/en/support-downloads/software/developer-tools/scanner-sdk-for-android.html
But my model MC33 is not in a list of approved devices. And test desktop app (supply in pack with SDK) does not detect my device.
Can somebody recommed what to do and if Zebra inc. plan to release SDK for my device (MC33) as well?
UPDATE: during debug my app catch answer code
112 = "ERROR_DEVICE_UNAVAILABLE" = " Required device is unavailable"
I work for Zebra and would concur with the comments below your question. The SDK you are using is designed for our range of handheld rugged scanners but the MC33 is considered a Mobile Computer and uses a different SDK.
I don't quite understand what you are trying to achieve by I'm developing a windows application with using scanner Zebra MC33. That device runs Android so if you want to send scan data to an application running on Windows you will first need to capture those scans on the device and then send them (through IP or BT for example) to your Windows desktop app. There are a few ways to do this (https://techdocs.zebra.com/help/) is a good entry point - you could use DataWedge to send the data over IP or you could write an Android app to send the data over a BT socket. There is a Xamarin SDK for C# development on the device that is popular with Windows developers but I don't think you mean that.
I'm working on an access control windows application, I'm using .Net and a simple Barcode readers.
In my app, I'd like to use 2 barcode readers installed on the same computer in differents USB ports
First to log entrance.
Second to log exit.
How can I retrieve which Barcode reader was been used to log ? (the one plugged on USB port 1 or 2)
>> here is an explanatory diagram
#Abd13t,
If you are using the scanner in keyboard wedge mode and both scanners are going to be reading the same barcode, one way to do this would be to add different prefixes that your scanner appends to the data event.
If you using an OPOS or POS for .NET implementation your data events should be associated with a specific device.
In order to help you further, we would need more details.

I am writing a BT app on an android to connect to a lab device/hardware. At the present time I have a device on loan. However it is not possible for me to always have one while I am developing for it, (commuting, out of town, etc) Therefore I am creating an emulator for it and will run that emulator on my Windows desktop so that my Android client code can make connections to it.
The android code is built with .NET/xamarin and works fine connecting to the real device.
I am comfortable with C++ or C# on the desktop.
I have found this code http://www.codeproject.com/Articles/252882/Bluetooth-Server-Programming-on-Windows online to create and accept BT connections. it looks like a very good start for what I wish to do - which is build a state machine/emulator to mimic the real device. However I have been unable to connect my android device to it.
Note - the connection is a serial port connection. (the UUI coming from the android device is the "well known" serial port connection ("00001101-0000-1000-8000-00805F9B34FB")
I am not sure how to configure the windows 7 desktop and bluetooth services to allow this server/emulator program to accept connections.
I have paired the devices, but unable to connect.
How can I accept incoming Bluetooth serial connections in the C++ or C# code running on Win7 desktop?
If you want to do low level stuff like establish a connection via bluetooth through a C# app then you will need to access the bluetooth stack via its API. If your device is running the Microsofts Bluetooth Stack then you can look at 32feet.net's managed wrapper for Microsofts Bluetooth API. If you have the Widcomm stack then you will have to locate Widcomm's API for it.
To access the microsoft bluetooth stack, you can use the BthUtil.dll.
BthUtil.dll is an unmanaged dll which is part of the Microsoft Bluetooth stack. It's typically utilised for tasks such as turning the bluetooth radio on or off via a function called BthSetMode
(see MSDN for documentation - http://msdn2.microsoft.com/EN-US/library/aa456007.aspx)

Also, check the 32feet.Net
A Brief description of 32feet.Net
32feet.NET is a shared-source project to make personal area networking technologies such as Bluetooth, Infrared (IrDA) and more, easily accessible from .NET code.
Supports desktop, mobile or embedded systems.
32feet.NET is free for commercial or non-commercial use.
If you use the binaries you can just use the library as-is, if you make modifications to the source you need to include the 32feet.NET License.txt document and ensure the file headers are not modified/removed. The project currently consists of the following libraries:-
Bluetooth
IrDA
Object Exchange
Bluetooth support requires a device with either the Microsoft, Widcomm, BlueSoleil, or Stonestreet One Bluetopia Bluetooth stack. Requires .NET Compact Framework v3.5 or above and Windows CE.NET 4.2 or above, or .NET Framework v3.5 for desktop Windows XP, Vista, 7 and 8.

I have to create an application for Honeywell Dolphin 6100 ; a mobile computer with a barcode scanner that uses Windows CE 5.0 like OS.
But I can not the find the relative librairies to make the interraction with the barcode scanner and the keyboard possible .
Does any one know any link that can help to find these librairies and may be some tutoriels that worked with the device ?
Thanks,
A simple search with a web search engine for "Dolphin 6100 SDK" turned up as the first result (with both Google and Bing) the Honeywell page for the device. Clicking on the "Software" tab on that page gets me a list with SDK v1.03 at the very top.
Please advice me, is there any built in function to retrieve "PID" and "VID" when USB is hooked up to the system? If not, what is the best way to get USB "HID" and "PID"? I need these two to detect USB HID device.
Since your tag specifies C# I'm going to assume that you want to do this using Microsoft Windows.
Using Windows I find this information using Device Manager under Computer Management (right-click on My Computer and select Manage). Using View -> Devices by connection open up the PCI bus node and then all of the USB nodes until you find the device you are looking for. Below is an example from my PC showing three USB devices on Intel(R) 82801G (ICH7 Family) USB Universal Host Controller entries.
Then look at the properties of the device -> then details -> then select property hardware ids and you should get the VID and PID of the device.
Don't know about native .NET, I only used LibUsbDotNet so far, check the examples.
Usually you would install the .NET assembly from the sourcefourge page, add the assembly to your Visual Studio project (References/.NET) and follow the examples (LibUsbDotNet Example Code/Getting Startet Example). Details depend on your C#/.NET/Visual Studio versions.
