[TESTING] Support for DVB adapters

Hello, I’m new to the forum so apologies if in the wrong place. I have just bought a Vero4K and the DVB-T2 from the osmac store. I have plugged it into a USN port, connected aerial connection, installed TVHeadend service from the app store then logged into tvheadend via my PC on the network. Whatever I do I cannot get tvheadon to see the DVB-T adaptor. I have honestly googled everything but cannot get this to work. My understanding is unless the adaptor is recignised in tvheadend then no point in continuing further. Please help.
