Mygica D692 + Docker

[stevil]

Trying for the first time to run NextPVR with a Mygica D692 in docker on Ubuntu 20.04.4 LTS, but nextpvr fails to see the device. 

Checking for the device "sudo dmesg | grep -i dvb" on the host:

[  13.883125] dvb-usb: found a 'Mygica D692 ATSC' in warm state.
[  13.884377] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
[  13.885498] dvbdev: DVB: registering new adapter (Mygica D692 ATSC)

[  14.460574] DVB: Unable to find symbol mxl692_attach()
[  14.460577] dvb-usb: no frontend was attached by 'Mygica D692 ATSC'
[  14.552312] rc rc0: lirc_dev: driver dvb_usb_cxusb registered at minor = 0, scancode receiver, no transmitter

[  14.552410] dvb-usb: Mygica D692 ATSC successfully initialized and connected.
[  14.552445] usbcore: registered new interface driver dvb_usb_cxusb


And looking at my compose

  nextpvr_amd64:
    volumes:
      - '$HOME/.config/appdata/nextpvr/config:/config'
      - '$HOME/.config/appdata/nextpvr/recordings:/recordings'
      - '$HOME/.config/appdata/nextpvr/videos:/buffer'
    devices:
      - '/dev/dvb:/dev/dvb'
    ports:
      - '8866:8866'
    image: 'nextpvr/nextpvr_amd64:latest'
    restart: always


Anything jump out?

Anything jump out?

that doesn’t look good. Sounds like maybe host is failing to load the drivers for the device.
