visual studio - using multiple usb rfid readers on a raspberry pi 3 running Windows 10 IoT and a c# universal app -

i'm hoping smarter me can come solution problem.

i have kiosk application has 2 usb rfid readers plugged raspberry pi 3 running windows 10 iot c# uwp app written in visual studio. rfid readers act keyboards. read id on rfid token "type" in , press enter.

i need able tell rfid reader reading tag @ given time.

using following project : http://www.codeproject.com/articles/17123/using-raw-input-from-c-to-handle-multiple-keyboard on windows 10 machine multiple usb rfid readers plugged in can tell rfid reader being used cannot work on raspberry pi running windows 10 iot core.

i have create uwp app using windows.devices.humaninterfacedevice namespace , can reader show cannot open it.

the code using is:

string selector = hiddevice.getdeviceselector(0x0001, 0x0006, 0x08ff, 0x0009); var hiddevice = await hiddevice.fromidasync(selector, fileaccessmode.read); var inputreporteventhandler = new typedeventhandler<hiddevice, hidinputreportreceivedeventargs>(this.oninputreportevent); hiddevice.inputreportreceived += inputreporteventhandler;  

when configure package.appxmanifest with:

<devicecapability name="humaninterfacedevice">   <device id="vidpid:08ff 0009">     <function type="usage:0001 0006"/>   </device> </devicecapability> 

and compile application error:

error dep0700 : registration of app failed. appx package's manifest invalid.: cannot register package because of problem function element usage:0001 0006: value blocked, , not allowed on bus (0x80073cf6)

so looks microsoft has blocked access rfid reader using windows.devices.humaninterfacedevice namespace (https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.humaninterfacedevice.aspx) because has been classed being in a top level application collection.

so options are:

1. try , raw input app working (from link codeproject site above) don't think work on pi due underlying calls making.

2. put different os on pi , rewrite kiosk application (i rather stick windows iot , c# uwp app.

3. think of different solution hope smart person reading post able suggest.

any suggestions welcomed!
