Skype Room System v3 app - Custom Themes?

Hi, Graham (or anyone else reading), did you ever find a solution to this? I'm struggling with a similar problem that I just can't make heads or tails of: The first part of my SkypeSettings.xml applies perfectly, with login info, servers etc, but then it fails every single time I try to define devices.

This is the devices part of my xml (this is for a test device, hence the non-standard devices):

<Devices>
<MicrophoneForCommunication>Logitech Webcam C930e</MicrophoneForCommunication>
<SpeakerForCommunication>Realtek High Definition Audio</SpeakerForCommunication>
<DefaultSpeaker>Polycom CX5100</DefaultSpeaker>
</Devices>

regards,

Øyvind
