Turris Omnia + LXC + USB dongle

I succesfully get working environment on OS X, now I would like to have it working on Omnia, in dedicated LXC.

I installed standard Ubuntu 16.04 and then followed steps described in tutorials:

When I plugged UDB dongle to Omnia I was able to see it connected, it identified itself as

Bus 002 Device 003: ID 0403:6015 Future Technology Devices International, Ltd Bridge(I2C/SPI/UART/FIFO)

The same was visible in Ubuntu running in LXC. However bcf devices did not show anything.

For Mac I had to install driver, however according site http://www.ftdichip.com/Drivers/VCP.htm it should be supported by Linux out of the box.

Any ideas what is wrong?

I have to try this setting, but from the past I know where the problem is, you have access to the given usb in the lxc container configuration?

I tested this setting, in Turris I started bcg as a service and joined mqtt in LXC.
