Astrometa DVB-T2 in LXC Debian problem

Have problem with USB Astrometa DVB-T2, model TVR801 (I think, because in dmesg is Realtek RTL2832P and Rafael Micro R820T).

Have Debian 9 - Stretch in Omnia LXC, Astrometa is visible in dmesg:

Problem is, that is no device in Tvheadend (Configuration -> DVB Inputs -> TV adapters).

U mě OK…
