[Intensity Pro] working fine but seeing Unknown Device?

I've just purchased an pre-owned Intensity Pro PCI-E card for some very basic device capture (RaspberryPi at low res) and it's working really well.

However in Device Manager (Windows 10x64) I'm seeing an "Unknown Device" listed which 100% is related to the card.

Blackmagic Audio, Blackmagic DeckLink WDM Streaming and Blackmagic Intensity Pro drivers are all installed successfully but something is very clearly missing.

Seeing as the card is working it's not a huge deal but for the sake of my OCD I'd like to resolve the driver issue.

Does anyone know what it is?

Thanks.

I'd be interested to know this too - same with the Ultastudio 4K Mini. Everything working fine but an extra unknown device in device manager.

It's just Micro$oft OS software
My guess is that the Mac OS platform gets better support by BMD....
