OSMC won't detect CrystalHD card on Apple TV 1

I have installed a Crystal Broadcom BCM970015 in ATV1. When I run OSMC and go to Settings > Video > Acceleration, “Allow hardware acceleration - CrystalHD” is grayed out. Is OSMC not detecting the card?

If you see CrystalHD, it’s detected. It’s greyed out because we don’t want people disabling the acceleration.

Great!! It works then!
Thanks very much
