BlackHole 1.7.1 usb-dtt tuner driver needed

Hi all,just installed B.H.1.7.1,I went to blue-blue,but can't see any option to install usb-dtt for terrestrial chnls.,which was in the previous ver.,am I missing something? Panic over,when I was configuring the tuners,it only showed tunerA andB,but having scanned in sats. and installed some plugins which necessitated a few restarts I now find tuner C is installed and enabled.

I scanned in the chnls.and it's working now,don't know how this happened but as long as it's working I'm happy.Thank you for your interest. Jolatacqce.
