Dockge and USB device - how does Dragonfish mount USB?

Hello all

I have a USB device (Coral TPU) which can be “seen” from within Dragonfish because an official app, Frigate, is able to exploit it.

I have installed jailmaker and I am running dockge (thanks @Stux !). I now want to run Frigate as a container via dockge & docker compose but to do so I need to tell the host where to mout the container resource. But I don’t know where the USB Coral TPU will be mounted by Dragonfish.

I have so far tried

HOST : CONTAINER

  • /dev/drv/usb:/dev/drv/usb
  • /dev/bus/usb:/dev/bus/usb
  • /dev/bus/usb/002/003:/dev/bus/usb/002/003
  • /dev/bus/usb/002/002:/dev/bus/usb/002/002

but I don’t really know what I am doing.

I have managed to get MotionEye, Hamclock and uptime-kuma to work via Dockge/jailmaker/TrueNAS but none of those require hardware resources to be mounted.

Can anyone help me find out where Dragonfish “mounts” the Coral USB TPU resource please?

See also here and here for similar questions which weren’t answered, so maybe this is something which can’t be done.
