any way to give access to host USB /dev/ttyUSB0

[roboto-cloud]

someone know how handling usb printer host from docker odoo:11 container?

I get this error:
docker logs odoo.dev

? odoo.addons.hw_escpos.controllers.main: Can not get printer description: [Errno 13] Access denied (insufficient permissions)

thanks in advance,

Have you tried volume mounting /dev/ttyUSB0 to the container?

hi @thomas15v :)
yes, I have mounted it in the docker-compose.yml

    privileged: true
    volumes:
      - /dev/bus/usb:/dev/bus/usb
      - /run/udev:/run/udev:ro

Does it work if you run odoo as root? (not recommended but useful for troubleshooting)

  user: root

You could also try to add "o+rw" to the device. Permissions are inherited between container and host.

You can also run without --privileged, it's a bit harder:

Is it solved ?

@roboto-cloud do you still have this issue? Can you close this issue if not needed?
