Problem/Motivation

Cannot access USB on RPi 3 Model B anymore, used for teleinfo reading. Was working before, didn't change my conf.

Expected behavior

Can read data from USB serial.

Actual behavior

Working fine directly in console on RPi

core-ssh:~# stty -F /dev/ttyUSB0 1200 sane evenp parenb cs7 -crtscts
core-ssh:~# cat /dev/ttyUSB0

But in NodeRed flow the Serial tile show not connected Parameters are identical:

• 1200 bits/s
• 7 bits
• even parity
• 1 stop bit

Steps to reproduce

Just try to read USB data from Serial bus in NodeRed 3

Proposed changes

None, except maybe a way to mount volume from host to container. I think it comes from this kind of thing.
