Yep. It's not clear from the image whether the connector is internal USB and the other lead is possibly for SpeakerLink comms in some way?

And of course, if USB, whether it's a standard USB audio driver bit like Explorer.

The comms bit is useful as I feel that if I ditched Sooloos and went with custom motherboard running say Roon, I would miss the integrated volume control and power on (via SpeakerLink) from the apps that Sooloos offers. At least if the SpeakerLink comms was available via the MC200 soundcard, it would give a fighting chance of implementing something.
