[VB.NET/C#] Lettore barcode su windows mobile

[foffo7]

Salve a tutti, io ho un palmare con Windows Mobile 6.5 con lettore di codice a barre integrato ed è quello che mi interessa, vorrei utilizzare i dati letti senza entrare in emulazione tastiera.
La casa produttrice (Symbol/Motorola) ha messo a disposizione delle librerie per farlo ed ho sviluppato il codice sia in VB.NET che in C#, ma nessuno dei due funziona perchè mi dice che non può attivare il reader qualcuno saprebbe aiutarmi?

VB.NET

Imports Symbol
Imports Symbol.Barcode
Public Class Form1

    Private MyScanner As Symbol.Barcode.Device = Nothing
    Private MyReader As Symbol.Barcode.Reader = Nothing
    Private MyReaderData As Symbol.Barcode.ReaderData = Nothing
    Private MyEventHandler As System.EventHandler = Nothing

    Private Sub MyReader_ReadNotify(ByVal o As Object, ByVal e As EventArgs)
        MsgBox(MyReaderData.Text, "HelloScan")
        MyReader.Actions.Read(MyReaderData)
    End Sub

    Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        MyReader.Actions.Flush()
        MyReader.Actions.Disable()
        MyReader.Actions.Dispose()
        MyReaderData.Dispose()
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        MyScanner = Symbol.Barcode.Device.AvailableDevices.First
        MyReader = New Symbol.Barcode.Reader(MyScanner)
        MyReaderData = New Symbol.Barcode.ReaderData(Symbol.Barcode.ReaderDataTypes.Text, Symbol.Barcode.ReaderDataLengths.DefaultText)
        MyEventHandler = New System.EventHandler(AddressOf MyReader_ReadNotify)
        AddHandler MyReader.ReadNotify, Me.MyEventHandler

        MyReader.Actions.Enable()
        MyReader.Actions.Read(MyReaderData)


    End Sub
End Class
