Hi Lewis,
Thank you for your quick response. I noticed that after installing PlantronicsURE-SDK.msi the “Plantronics.devices.common” assembly is available from within Visual Studio (picture 1), but after installing Spokes_RT.msi (minimal runtime Spokes) this assembly is no longer visible (picture 2). This causes problems when developing an application in Visual Studio, but the final application works correctly anyway.
I have one more question - what is the property “EnableDeviceFilter” in DeviceManager class?
Thanks,
Michał
